The Airstream Interstate 24X is the brand's purpose-built off-road Class B, riding on a Mercedes Sprinter AWD/4x4 chassis that opens up terrain most campervans won't touch. A lithium battery bank and solar setup mean genuine boondocking capability, not just a marketing claim. The wet bath layout keeps things compact but functional, and Airstream's well-known attention to detail and build quality carries over here, along with the resale value that tends to follow the brand. It's a premium buy at a premium price, but for an overlanding-style Class B with serious go-anywhere credentials, the Airstream Interstate 24X has few direct rivals.
Other class b motorhomes floor plans (around 24 ft 6 in, near $265,000), similar in size and price to the Interstate 24X.
