Flow Path Explanation

The raised shower system works by elevating the shower pan enough to allow a drain line to flow into a compact sump pump box.
The sump pump then automatically transfers water into the interior gray tanks.

  • 1. Raised Shower Platform: Provides vertical space for the drain and plumbing beneath the pan.
  • 2. Low-Profile Drain: Minimizes height while allowing a 1″ outlet to feed the sump box.
  • 3. Sump Pump Box: Collects water and pumps it upward or horizontally to the gray tanks.
  • 4. Interior Gray Tanks: Store all wastewater inside the insulated trailer envelope.

Why This System Works for an Interior-Only Plumbing Layout

This configuration supports the goal of keeping all plumbing and tanks inside the trailer, avoiding exposure to road debris, freezing temperatures, and under‑frame clearance issues.

  • No exterior tanks: All tanks remain inside the conditioned space.
  • Freeze protection: Interior placement prevents winterization issues.
  • Flexible routing: Pumped discharge allows tanks to sit higher than the shower.
  • Compact footprint: Marine components are designed for tight spaces.

Notes for Final Design

  • Confirm sump box placement for easy access to the lid and pump.
  • Plan for a service hatch or removable panel in the shower platform.
  • Use smooth‑bore hose for the pump discharge to reduce backpressure.
  • Ensure gray tank inlet height matches the sump pump’s lift capability.

This diagram will serve as a reference as the bathroom plumbing system is finalized and integrated into the overall trailer layout.

Shower Drain Components Under Consideration for the Bathroom Build

Shower Drain Components Under Consideration for the Bathroom Build

As I plan the raised shower platform for the bathroom, I am exploring different components that will allow the shower to drain directly into the interior gray tanks.
Keeping all tanks inside the trailer is a priority for freeze protection, maintenance access, and overall system reliability.
Two products that may play a role in this design are a low-profile shower drain and a compact 12V shower sump pump box.

Scandvik Low Profile Drain Stopper – 1″ Outlet


Scandvik Low Profile Drain Stopper – 1″ Outlet

This drain is designed for marine environments where space is limited and drainage must be routed through tight areas.
Its low-profile design makes it a strong candidate for a raised shower floor where vertical clearance is limited.

  • Outlet Size: 1 inch
  • Design: Low-profile for tight installations
  • Intended Use: Marine showers and wet areas
  • Potential Benefit: Allows the shower pan to sit lower while still routing water into a sump box

This drain could be mounted directly into the raised shower platform, feeding into a sump pump box located beneath or adjacent to the shower structure.

Zuomeng 12V Automatic Shower Sump Pump Box – 750 GPH


Zuomeng 12V Automatic Shower Sump Pump Box – 750 GPH

This sump pump box is designed for boats and RVs to collect shower water and automatically pump it to a gray tank.
For a cargo trailer conversion with interior tanks, this type of system allows the shower to drain efficiently even when the gray tanks sit higher than the shower pan.

  • Brand: Zuomeng
  • Flow Rate: 750 GPH
  • Power: 12V DC (corded electric)
  • Material: ABS housing
  • Maximum Lifting Height: 10 feet
  • Item Weight: 4.64 lbs (2.11 kg)
  • Package Dimensions: 12.05″ × 10.55″ × 5.67″
  • Model Number: HY-056
  • Included Adapters: 3/4″, 1″, and 1-1/8″ hose fittings

The sump box collects water from the shower drain and automatically pumps it into the gray tanks, making it ideal for raised shower platforms or installations where gravity drainage is not possible.

How These Components Fit Into the Shower Design

The raised shower platform will allow the drain to sit above the sump box, which then pumps water into the interior gray tanks.
This approach eliminates the need for any tanks mounted under the trailer and keeps all plumbing inside the insulated envelope.

  • Low-profile drain: Minimizes height while providing a clean outlet into the sump box.
  • Sump pump box: Automatically moves water to the gray tanks regardless of tank height.
  • Interior-only plumbing: Improves freeze protection and simplifies maintenance.

These components are being documented here as part of the ongoing evaluation process for the bathroom plumbing system.
Final selections will be made once the shower platform height, tank placement, and plumbing layout are fully defined.

Marine Grade DC Wiring Under Consideration

Marine Grade DC Wiring Under Consideration

For the 12V DC side of this cargo trailer conversion, I am strongly leaning toward using
marine grade wiring rather than standard automotive or household wire.
Because this build will be mobile and exposed to varying temperatures, humidity, and potential condensation,
moisture resistance and corrosion resistance are important factors in the wiring choice.

One specific product I am considering is:


12 Gauge Wire 3 Core Conductor Triplex Twin and Earth Marine Grade 12AWG Electrical Cable – SAKAKI

Product Overview

This cable is a 12 AWG, 3-core, flat triplex “twin and earth” marine grade wire designed for low-voltage DC applications.
It is intended for use in boats, automotive environments, and other mobile installations where vibration, moisture, and corrosion are concerns.

  • Type: Flat Triplex Twin and Earth Marine Grade Cable
  • Gauge: 12 AWG (12/3 wire – three conductors)
  • Conductors: Stranded, tinned copper
  • Insulation: PVC insulated
  • Voltage Rating: 300V (suitable for 5V, 12V, 24V up to 300V)
  • Waterproof Level: IP68
  • Working Temperature Range: -68°F to 176°F
  • Flame Retardant Grade: VW-1
  • Intended Use: Marine, automotive, and other mobile low-voltage applications

Why Marine Grade Wiring Is Being Considered

The cargo trailer conversion will experience vibration, temperature swings, and potential moisture from condensation and outdoor conditions.
Marine grade wiring offers several advantages in this environment:

  • Tinned copper conductors: More resistant to corrosion than bare copper, especially in humid conditions.
  • Stranded and flexible: Better suited for vibration and movement than solid conductors.
  • IP68 waterproof rating: Provides a high level of protection against moisture ingress.
  • Wide temperature range: Suitable for both hot and cold operating conditions inside a trailer.
  • Flame retardant insulation: Added safety in an enclosed space.

Potential Uses in the Build

If selected, this 12 AWG 3-core marine grade cable could be used for:

  • 12V DC branch circuits (lighting, fans, small loads)
  • Runs where multiple conductors in a single jacket are helpful for organization
  • Areas where moisture or condensation is more likely (near exterior walls, floor cavities, or utility chases)

The flat triplex configuration also helps with cable management and routing, keeping related conductors bundled together in a clean, repeatable way.

Notes for Future Evaluation

  • Confirm ampacity and voltage drop for planned circuit lengths and loads.
  • Compare cost versus standard automotive primary wire and duplex marine cable.
  • Plan routing paths to take advantage of the flat triplex form factor.
  • Verify compatibility with planned fuse blocks, terminals, and distribution hardware.

This page is intended as a reference for the type of wiring being considered.
Final wire selection will be made after the electrical layout and load calculations are fully defined.

EcoFlow DELTA Pro 3 – Portable Power Station

EcoFlow DELTA Pro 3 – Portable Power Station (Reference for Consideration)

As I continue evaluating electrical system options for the cargo trailer conversion, I am now considering a broader EcoFlow ecosystem that includes the
DELTA Pro 3 Portable Power Station, the EcoFlow Smart Generator 4000 (Dual Fuel), a 50‑amp shore power inlet, and a future solar charging setup (roof‑mounted or portable).
This post documents the DELTA Pro 3 as a potential core component of that system.

This page is for reference only. I have not selected this unit for the build, but I am documenting it here as a potential option worth evaluating.

Product Overview

The EcoFlow DELTA Pro 3 is a high‑capacity portable power station designed for home backup, off‑grid use, and mobile applications. It combines a large lithium iron phosphate (LFP) battery, inverter, charger, and distribution system into a single integrated unit.

  • Dual Fuel: Gasoline or propane
  • Smart Charging: Automatically charges the DELTA Pro 3 when battery levels drop
  • High Output: Designed for fast, efficient charging
  • EcoFlow Integration: Controlled through the app or linked directly to the power station

50‑Amp Shore Power Inlet

I am leaning toward installing a 50‑amp shore power inlet on the trailer.
This would allow the DELTA Pro 3 to charge quickly from campground hookups or home power, while also providing a stable AC source for high‑demand appliances.

Solar Charging (Portable or Roof‑Mounted)

Solar will be part of the system, though I have not yet decided between:

  • Portable solar panels for flexible positioning and maximum sun exposure
  • Roof‑mounted solar array for convenience and continuous charging while parked

The DELTA Pro 3 supports high‑wattage solar input, so either option—or a combination—can be integrated.

Why This System Is Worth Considering

The DELTA Pro 3 ecosystem offers several advantages for a cargo trailer conversion, especially for a build that prioritizes simplicity, modularity, and safety.

  • Plug‑and‑play operation: No need to design or wire a full inverter/charger/battery system.
  • High output power: Capable of running HVAC, induction cooking, and other heavy loads.
  • Expandable capacity: Additional batteries can increase total storage up to 48kWh.
  • Multiple charging options: Shore power, solar, generator, EV charger, or vehicle alternator.
  • UL9540 certification: Provides a high level of safety for indoor installation.
  • Integrated generator support: The Smart Generator 4000 adds reliable backup charging.
  • Portable and removable: The system can be taken out of the trailer if needed.

Limitations to Keep in Mind

  • Recharge dependency: Solar, shore power, or a generator is still required for extended off‑grid use.
  • Cost: Higher upfront price compared to a DIY battery/inverter system.
  • Weight: Large portable units add significant weight to the trailer.
  • Integration limits: May not replace every component of a full RV electrical system.
  • Generator noise: Even efficient generators produce some noise during charging.

How This Could Fit Into the Trailer Build

If selected, the DELTA Pro 3 would serve as the primary power hub for the trailer.
The Smart Generator 4000 would provide backup charging, the 50‑amp shore inlet would support fast AC charging, and solar would maintain battery levels during daily use.

This approach simplifies the electrical system while still offering enough power for HVAC, appliances, and tools planned for the build.

Notes for Future Evaluation

  • Confirm output capacity aligns with HVAC and appliance requirements.
  • Evaluate total weight and placement inside the trailer.
  • Compare cost and flexibility against a traditional inverter + battery bank system.
  • Determine solar capacity and whether portable or roof‑mounted panels make more sense.
  • Review generator noise levels and fuel storage considerations.

This page will continue to evolve as I refine the electrical system design and evaluate the full EcoFlow ecosystem for the build.

Black Water Tank Install

Cargo Trailer Camper Conversion – Black Water Tank Install

As part of researching different plumbing layouts for this build, I found a helpful reference video titled
“Cargo Trailer Camper Conversion – Black Water Tank Install” by Be Free Builds.
This video walks through the process of mounting a black water tank under a cargo trailer and adding the basic plumbing components needed for a toilet installation.

You can watch the video here:

Cargo Trailer Camper Conversion – Black Water Tank Install

Black Tank Installation on Custom Cargo Trailer Camper Toy Hauler RV DIY Van Conversion Bathroom

What the Video Covers

The creator demonstrates the full installation process for an under‑mounted black water tank, including:

  • Tank positioning between the trailer frame rails
  • Mounting method using metal straps and wood blocking
  • Cutting openings for the toilet inlet and drain fittings
  • Basic plumbing connections for the toilet and venting
  • Securing the tank to prevent movement during travel

The video provides a good visual reference for how a black tank can be mounted beneath a cargo trailer, especially for DIY conversions where space is limited.

Key Takeaways

  • Frame spacing matters: The tank must fit cleanly between the frame rails without interfering with crossmembers.
  • Strap protection is important: Several commenters note the need for rubber padding between metal straps and the tank to prevent wear over time.
  • Vent routing: The video shows the tank installation but does not go in-depth on vent placement; this is something to plan carefully.
  • Ground clearance: The tank sits below the floor line, so clearance must be considered to avoid bottoming out.
  • Wood vs. metal bracing: Some viewers recommend replacing wood blocks with steel for long-term durability.

Why This Video Is Useful for My Build

Even though my build will not use a black water tank (composting toilet), this video is still valuable for understanding:

  • How tanks are mounted under a cargo trailer
  • How plumbing penetrations are cut and sealed
  • How much space tanks require beneath the floor
  • What to avoid (sharp edges, unsupported weight, low clearance)

This reference helps inform decisions for my fresh water and grey water tank installations, as well as general under‑frame routing and protection.

Additional Notes

The comments section includes useful feedback from other builders, including suggestions for:

  • Using rubber padding or tire rubber between straps and tank
  • Upgrading to steel bracing instead of wood
  • Ensuring proper venting through the wall or roof
  • Checking tank clearance when fully filled

As I continue planning the plumbing system for this build, I’ll reference this video for mounting ideas, strap design, and under‑frame layout considerations.

Bed Option: Storage‑Focused Wall Bed System

Alternate Murphy Bed Option: Storage‑Focused Wall Bed System

I’m also looking at another Murphy bed option for the Cargo Trailer Conversion — this one is significantly larger,
but it brings a ton of built‑in storage that could simplify the bedroom layout.

Red Barrel Studio – Storage Murphy Bed with Wardrobe, Bookcase & Drawers

  • Anchoring: The unit will need to be secured into the trailer’s wall studs and possibly the floor to prevent movement during travel.
  • Clearances: The fold-down path and sofa depth must align with the bedroom layout and walkway space.
  • Ventilation & Airflow: The bed position should not obstruct HVAC airflow or access panels.

Why I’m Leaning Toward This Model

This Murphy bed aligns with the overall design philosophy of the build:
flexibility, comfort, and efficient use of space.
It allows the bedroom to function as both a sleeping area and a daytime living space without requiring major structural modifications.

As the build progresses, I’ll update this page with installation notes, anchoring methods, weight details, and final photos once the unit is installed.
