Used motorhomes and travel trailers can sell for only a few thousand dollars, but repair costs can exceed the vehicle's market value. Complete roof replacement, severe water damage with wall delamination, diesel engine replacement, transmission replacement, full floor replacement, and slide-out structural repairs can run into tens of thousands of dollars on older units. For example, a $6,000 travel trailer with severe water intrusion may need structural work worth more than its resale value, while a $20,000–$30,000 motorhome with engine failure can face a bill approaching or exceeding its market price.
