I think what you'll find is that assuming somebody else's RV loan is a violation of the loan contract. There is likely far more danger to the original owner of the motorhome than the leaser, but you both could lose. What happens when you slap down the $10k and then the bank finds out and comes and repos the motorhome from you. You think you'll get your $10k back? Also if somebody is having somebody else assume a loan versus just selling the motorhome, that means their upside down in it. That means you are potentially buying a motorhome that is not worth what you're paying for it, assuming you want to keep the motorhome.
