I would first talk to the bank. We have some bankers on this site might give you good advice. If the bank loans you the money, I would expect a hefty pre-payment penalty. They don't like to go to all that work for nothing. I would just go to a well established dealer, make a deal on the rig. Tell them that's the out the door price so they on't stack fee's on top.Buy it off the lot is what I mean. Then come back with a cashiers check and you'll have your RV. If it's a long standing reputable dealer, there shouldn't be a problem.
