Engineer's Dream RV: A Deep Dive into this Insane DIY Truck Camper Build

Mark, a mechanical engineer, and his wife Ellen, an interaction designer, embarked on a 3-year journey to build their ultimate DIY truck camper. Tired of existing RV limitations, they combined their expertise to create a custom composite-bodied camper loaded with innovative features. This article delves into the technical details and thoughtful design choices that make this build a true engineering marvel, as seen on New Jersey Outdoor Adventures' YouTube channel.

Composite Construction and Structural Integrity

The camper's foundation is a meticulously engineered composite box, constructed from fiberglass and polyurethane foam. The sidewalls boast a 50mm thickness, while the roof and floor are an impressive 83mm thick, providing exceptional insulation. Mark emphasizes the importance of the zero-torsion subframe, stating, "The box is sitting on a sub chassis that protects it from the movement of the truck chassis. So, it's a zero torsion subframe." This subframe isolates the camper from the truck's frame, minimizing stress and ensuring longevity. Furthermore, steel tubing is integrated and bonded inside the composite panels, adding structural support where needed for load-bearing items like the bunk bed and dinette.

Mark also detailed the CNC machined lightweight wood construction inside the RV. He demonstrated this by removing the cover to their battery compartment: "Each and every wooden panel in here is a a birch plywood panel that's been CNC machined out the back. And on the other side, we have that genuine bamboo veneer. So these are incredibly lightweight. And this construction is in every single component of the of the camper."

The exterior features Arctic Curve windows with built-in blackout shades and bug screens, designed for optimal ventilation in any weather. Even in cold conditions, the windows can be slightly opened to prevent condensation, a testament to the thoughtful design that prioritizes comfort and functionality.

Electrical System and Power Management

The heart of this camper's electrical system is a robust array of components housed in a dedicated side compartment. It features 600 amp-hours of lithium batteries, a 2400-watt inverter, and a solar charge controller for the 1300 watts of solar panels mounted on the roof. This setup allows for significant off-grid capabilities. Mark highlights the importance of efficient power management, noting that the camper is equipped with a Simarine systems monitor screen, offering precise control over various electrical functions, including AC hot water heating, diversion load management for solar panels, and the operation of the rear motorized deck.

Ellen's expertise as a user experience designer shines through in the power panel's layout. She designed the controls for the lighting and other systems with ease of use in mind. Switches are strategically placed, and critical functions like the yellow and gray tank dumps require double activation to prevent accidental operation. These details showcase a deep understanding of user needs and a commitment to creating a seamless and intuitive living experience.

The lighting system itself is noteworthy, utilizing 4000K color-matched LEDs throughout the camper. A remote control allows for convenient adjustment of the lighting, while master mechanical switches provide a backup. Ellen explained that the lights are organized front to back, helping users easily identify which lights they are controlling. She also integrated a timer that automatically turns off the lights after three minutes, promoting energy conservation.

Innovative Features and Custom Modifications

One of the most striking features of this custom RV is the motorized rear deck, which extends electronically to create a spacious outdoor platform. This platform serves multiple purposes, from a place to relax and enjoy the scenery to a convenient spot for showering or bathing the dogs. The deck's versatility is further enhanced by the bicycle rack, which slides out with the deck, ensuring that bikes can be easily transported and accessed.

The interior is filled with ingenious space-saving solutions, such as the convertible bunk beds. These beds can be transformed into a couch or a buffet, maximizing the usability of the living area. The upper bunk even uses the same Richlite material as the kitchen countertop, creating a seamless and cohesive design.

Mark also designed a foot-operated water switch for the kitchen sink. He mentions that this design element was a direct result of living in an RV for many years. "It was always the conversation, did you can you turn the water pump on? Can you turn Oh, did you turn the water pump off? Oh, I'm not sure. Let's go around and check it. was like a constant discussion of that and this just completely solves that problem."

Truck Modifications and Off-Road Capability

The truck itself is a heavily modified 2005 Dodge Ram 3500, with significant upgrades to the frame, suspension, and braking system. Mark rebuilt everything from the back of the cab to ensure it could handle the weight of the camper. The truck now boasts new springs, heavy-duty brakes, and a zero-torsion subframe. These modifications ensure optimal performance and safety, even on challenging terrain.

He upgraded to Method 701 bead grip wheels with Nitto Recon Grappler tires. The whole truck is riding on Fox 2.5 inch shocks and heavy duty springs in the front and 14,000lb leaf springs in the back. The front steel bumper houses a 12,000lb winch, off-road lights, and an antenna for a ham radio. A 50-inch LED light bar is mounted above the cab, providing ample illumination for nighttime adventures.
