Roadtrek Camper Vans: Zion, SS Agile & More

The entry gateway is the Play, an 20‑foot‑11‑inch ProMaster 3500 build that keeps MSRP approachable while loading in the essentials: rear power sofa that converts to a queen, a one‑piece wet bath, Truma Combi heat, 200 watts of roof solar, and dual AGM batteries. Add the Play + trim and you gain upgraded cabinetry, a larger fridge, and extra exterior paint options while sticking with the same Pentastar V‑6 drivetrain and nine‑speed automatic that any Stellantis dealer can service.

One step up, the Chase extends the ProMaster to 20 feet 9 inches and adds creature comforts for couples who tour year‑round. The rear 6‑inch‑thick cushion set forms twin beds or a 74‑inch king, while the Duo Space wet bath pivots its wall to keep the toilet and sink dry during showers. Standard gear includes a 2,000‑watt inverter, 300 watts of solar, heated plumbing, and heavy‑duty AGM batteries; an optional folding mattress across the cab seats raises sleeping capacity to three without adding length.

Roadtrek’s best‑selling family is the Zion series, all on the ProMaster 3500 159‑inch wheelbase. The core Zion offers an open aisle for bikes and kayaks, a 30‑gallon fresh tank, and opposing bench seats that convert to either twin beds or a 74‑inch king. Variants multiply the formula: Zion SRT compresses the same amenities into a 19‑foot shell for stealth parking; Zion Slumber grafts a molded fiberglass pop‑top onto either body length for an extra loft bed; Zion Slumber SRT does the same on the short van. Every Zion carries a 3.6‑liter V‑6, 5,000‑pound hitch, and upgrade path to 460‑Ah lithium power, turning it into a quiet, generator‑free basecamp.

For Mercedes refinement in a compact package, the SS Agile rides on the 144‑inch Sprinter 2500 and measures just 19 feet 5 inches bumper to bumper. A 2.0‑liter twin‑turbo diesel feeds a nine‑speed automatic and available AWD, while inside you’ll find Ultraleather seating, a power sofa that forms a 70‑inch bed, induction cooktop, and a diesel hydronic furnace that sips from the Sprinter’s tank—no propane required. A 330‑Watt solar package and optional 600‑Ah lithium bank power the 13.5k‑BTU A/C off‑grid, and five belted seats make SS Agile a nimble people‑mover Monday through Friday.

Newest to the stable, the Pivot family blends social space with flexible sleeping on the ProMaster 3500. Behind the swivel cab chairs sit two forward‑facing benches with belts for four; aft, raised twin beds transform into a king above cavernous gear storage. A pivoting bath wall isolates the shower from sink and toilet, and a Firefly touchscreen links lighting, tank levels, and 13.5k‑BTU Aventa Eco A/C. Standard spec brings 300 watts of solar, 400‑Ah AGM batteries, and a 2,000‑watt inverter; the Pivot Slumber adds an elevated pop‑top loft, boosting sleeping capacity to five without changing exterior dimensions.

From the budget‑friendly Play to the deluxe SS Agile, and from Zion’s gear‑garage aisle to Pivot’s convertible lounge, Roadtrek’s 2025 Class B collection shows how one builder can tailor the Ram ProMaster and Mercedes Sprinter platforms into five very different adventures—each tuned for reliability, four‑season comfort, and the on‑the‑road spontaneity that defines van life.
