Why get a heavy-duty pickup truck with a camper on top other than to tow fun toys to your next vacation or outing. This is precisely what I am doing with this Ram HD Cummins that is equipped with a Four Wheel Camper on top of it. It’s a one-ton 4×4 overland truck with camper accommodations for four and plenty of towing capacity to pull a boat. I go on a lake trip to find out exactly how this camper tows a 6,000 lbs boat and what fuel efficiency it gets.

This is brought to you by our friends at Four Wheel Campers. Take a look at their website if you want to learn more about the Norweld aluminum flatbeds or the spacious Hawk Flatbed camper.

The truck is a new 2021 Ram HD 3500 single-rear-wheel configuration that originally came with an 8-foot bed. The bed was removed in favor of a new Norweld aluminum flatbed. The bed itself is equipped with many lockable storage boxes, a slide-out drawer, and a built-in water tank.

The truck got a suspension lift with Bilstein shocks and 37-inch MAXXIS off-road tires on TrailReady beadlock-capable wheels. Front and rear bumpers were swapped for extra heavy-duty TrailReady off-road bumpers that still accommodate proximity sensors and integrate well into the truck.

The Four Wheel Camper Hawk itself has a side entry door on the passenger side, a dinette that converts into either a bed or an indoor shower. The over-the-cab expandable bed can accommodate up to three people. The camper is also equipped with a larger refrigerator, stove, sink, and a cassette toilet.

The 6.7-liter Cummins I6 turbo-diesel in this Ram 3500 is a standard output engine. The high-output version that comes with the Aisin 6-speed transmission is optional. This engine is rated at 370 horsepower and 850 lb-ft of torque. It uses Ram’s 68RFE 6-speed automatic transmission. This may not sound like a lot of power for a large and heavily equipped truck like this, but it tows the 6,000 lbs boat without breaking much of a sweat. It is very impressive. It’s easy to get up to highway speeds. The tow/haul mode and variable exhaust brake help to slow the whole rig down.

Take a look at the video below to see what MPG I got on my 100+ mile roundtrip with the boat in tow.
