Friends just bought a Mercedes Sprinter fully tricked out RV for travel. They spent in the high 100s for it. It’s really nice, but close to $200k? Yikes!
Other friends have a 22 ft RV with a bed over the cab. The chassis / cab is a Ford F300 (I think), so very heavy duty. They splurged on super mattresses which they like a lot. When they visited this summer, they preferred to stay in their rolling home in our driveway rather than our guest room.
