Crappy RV
Wikisimpsons - The Simpsons Wiki
The Crappy RV is a vehicle which was used and wrecked, then being sold to Bob's RV Round-Up, where they sold it for next to nothing. It was the only RV that Homer could afford, so he takes it. It is bad and always backfires, it is falling apart and smells. Yet, the Simpsons go on their family vacation in it. Homer doesn't use maps, so ends up driving it straight through Springfield National Forest and almost plunging it off Tenderfoot Gorge. The Simpsons escape, but the RV falls down and expodes..
