Kestrel Take

The luxury Class B — Airstream's Interstate on the Mercedes Sprinter chassis is beautifully finished, plush, and holds value like few RVs. It's a genuine premium van camper. The trade-off is Sprinter diesel service/emissions and the cost of Airstream's premium systems. A well-maintained Interstate with documented Sprinter service and a sound house system is a superb, high-resale luxury camper; verify the diesel history, electrical, and for leaks.
