The Zion from Roadtrek is a Class B camper van built on a Ram ProMaster 3500 extended chassis in Cambridge, Ontario. Its big idea is an open center aisle: instead of packing the middle of the van with furniture, Roadtrek leaves room to roll in bikes, kayaks, and other gear, then turns the back into a king bed at night. It seats five and sleeps up to three.
Built for Gear and Getaways
The Zion rides on a Ram ProMaster 3500 with a 159-inch extended wheelbase, a 3.6L V6, and a 9-speed transmission. At about 20’9″ long, the Zion is a full-size ProMaster van. Outside, it comes with a 13,500 BTU Truma rooftop air conditioner, a power awning, an outdoor shower, bug screens on the side and rear doors, power steps, and 300 watts of solar on the roof.
A Rear Sofa That Becomes a King Bed
At the back, a power sofa with seatbelts works as seating during the day. At night, it can be set up as two twin beds or folded into one king bed. An optional folding mattress across the front captain’s chairs adds a third sleeping spot, and there’s also an optional forward-facing sofa layout.
Galley, Lounge, and Wet Bath
The galley has a 5.3 cubic foot refrigerator, a propane stove, a microwave, and a flip-up counter extension with a charging station, plus a slide-out pantry and a large pot drawer. A Firefly touchscreen controls the van’s systems, and an automatic propane heater keeps it warm on cold nights.
Inside, there’s a wet bath with a marine toilet, a sink, and a shower, so you’re not dependent on campground bathrooms.
