2 tips that I was given that I will pass on.
RV's will be cheaper just before winter when a buyer wants to sell and surely does not want to pay for a whole winter storage on an RV he no longer wants. (of course this only works in the states that do have a winter):W
And if you have some extra money you can use for air fare, expand your search for RV's down in Florida and in other states for that matter and fly down to get it and drive it back.
I am down here right now and the prices on used RV's are WAY lower than anywhere else. Many RV'ers come here to retire and pass on and their kids just want the RV gone. And because there are so many RV's in Florida, with the law of supply and demand the prices on used are just simply lower.
