Want to cancel RV sale as wife lost job - how can we?

Sorry to post again but this dealer goes against my grain. To give someone a paper that clearly says QUOTE on the front then; in small print on the back says it is a purchase agreement with conditions. This I consider a very deceptive business practice. Should you decide to purchase an RV I would suggest you get away from this dealer and buy somewhere else. He has shown you his true colors.
