2026 Thor Tranquility for Sale

The Tranquility is Thor Motor Coach's step up the chassis ladder: a Mercedes-Benz Sprinter all-wheel-drive diesel camper van that trades the gas ProMaster line's low price for a premium drivetrain, all-weather traction, and a more refined ride. Offered across a range of lengths from roughly 19 to 24 feet (plans like the 19P, 19M, 24A, and 24C, plus a 4x4-flavored 19R), it pairs the turbo-diesel Sprinter with Thor's Re(Li)able energy system powered by Fathom e-power — a full lithium-ion power-management package — along with a wet bath, a full galley, and twin-to-king or chaise sleeping arrangements depending on the floor plan. This is the van for buyers who want Mercedes drivability and AWD confidence for snow and light gravel, in a Thor priced below the boutique Sprinter builders. The honest trade-offs are real: the Sprinter AWD chassis pushes the Tranquility into the low-$200,000s, far above the gas ProMaster Thors and into specialized-service territory, and like the rest of the line it carries thin individual review coverage and the brand's roughly 3.0-star Class B rating, so inspect for the quality-control issues owners report. For a buyer who wants an all-weather diesel van with a premium chassis at a relative discount, the Tranquility is Thor's most capable camper van.
