Does This Furniture Truck Have Every Offroader's Dream Setup?

Converting a furniture truck into the ultimate off-road hauler sounds like something only a mad scientist would attempt, but the crew at WilsonFab proved it’s not just possible - it’s brilliant. Their 1997 International 4700 transformation shows what happens when you take years of wheeling experience and channel it into solving every problem you’ve ever faced on the trail.

Most people think toy haulers when they picture hauling their rigs to remote wheeling spots. The WilsonFab team thought bigger. Way bigger. They started with a commercial furniture truck and turned it into what they call “Das Tortoise” - a 37-foot beast that can haul a full-size crawler while keeping you comfortable for weeks off-grid.

The heart of this monster is a DT466E International engine backed by a Spicer six-plus-one manual transmission. That powertrain choice wasn’t random - they needed something bulletproof enough to pull serious weight across the country without breaking a sweat. Two 60-gallon diesel tanks give this rig about 1,200 miles of range, which means fewer fuel stops and more time getting to the good stuff.

What makes this build special isn’t just the size - it’s the thinking behind every modification. These guys got tired of dealing with weather, theft, and the general hassle of traditional trailer setups. Their solution was cutting a pass-through behind the cab seats, creating a seamless connection between the driving area and living space. No more stepping outside in nasty weather just to grab something from the back.

The garage section shows serious engineering thought. Those loading ramps don’t just drop down - they’re designed so the crawler can drive over built-in ramps that protect a 120-volt air compressor with a 25-gallon tank. Spare tires, leveling blocks, and even the big 42-inch Pitbull Rockers all have designated spots. Four 5,000-pound tie-downs bolt directly to the frame, not just the body, because nobody wants their rig shifting around during a cross-country haul.

Living space rivals most RVs but with way more durability. The interior runs completely off-grid with solar panels feeding a battery bank that includes marine deep cycle and bulldozer batteries. A 4,000-watt generator handles the heavy electrical loads and mounts underneath on an ATV winch system - no tools needed to deploy it. The whole setup can run that generator while driving if needed.

The kitchen setup includes a full-size propane refrigerator and freezer, stove, oven, microwave, and 15 gallons of fresh water. Computer fans keep the refrigerator cool in desert heat. The bathroom is fully functional with shower, toilet, and proper black water system. A queen bed up top and fold-down twin beds mean this thing sleeps a crew comfortably.

But the real genius shows in the details. An EGT gauge and boost gauge monitor engine health from the cab. The winch controller runs inside for self-recovery without getting out. Backup cameras help navigate tight spots with 37 feet of truck. Even the spare parts selection shows experience - they carry everything from serpentine belts to a spare ECM wrapped in multiple layers of protection.

The fabrication side of the garage holds a Hobart 180 MIG welder, welding gas storage, and a hitch-mounted vise. These aren’t weekend warriors - they’re prepared to fix anything that breaks, anywhere it breaks. The tool selection includes a 20-ton jack and everything needed for roadside tire changes.

Two layers of six-millimeter bubble insulation keep the interior comfortable in extreme temperatures. All lighting is LED to reduce power draw. The AC keeps things cool in 95-degree heat while the furnace handles cold weather. This truck was built for year-round use in any climate.

The ultimate test came during their King of the Hammers run in 2018. Eastern Virginia to California in 48 hours, then back in 46 hours, completely self-sustaining the entire trip. That’s when “Das Tortoise” earned its name - slow and steady, but absolutely unstoppable.

This build represents everything right about the off-road community. Instead of complaining about problems, they engineered solutions. Instead of accepting limitations, they built something better. The result is a mobile base camp that can handle weeks in the backcountry while protecting your rig and keeping your crew comfortable.

Most importantly, this isn’t some show truck that never sees dirt. This is a working machine built by people who actually use their equipment. Every modification serves a purpose learned through real experience. That’s what makes it so impressive - and so effective.
