We just purchased a newer model class B to travel and are selling our very old but still running well class B van.

Yes miles are high. But it's been mostly on the highway and driven in Midwest states with minimal stopping and going between cities.

Everything should be working for it's age. We replaced the fridge, added a TV by the bed, and a few cosmetic changes.

Yes it's cheap with it's age and mileage. We feel it's a fair price considering you can live in it or travel around locally. With higher miles you probably won't tour the country.
