MOST IMPORTANT POINT!!!
NEVER purchase an RV in a state that doesn't have STRONG "Lemon Laws" that cover the RV. I made that mistake in Elkhart, Indiana. After a continuing nightmare, my legal advisor said nothing could be done. Lemon laws will help protect you!
I also advise purchasing an RV that has a factory close to your home.......cause you are gonna spend some time there getting it fixed. Local RV dealer's service departments are usually a bad joke. Hundred bucks an hour for service, and the kid working on your RV........well lets just say his last job must have been working the drive-through at McD's.
No I am not saying all dealers are bad, but the majority that I have delt with leave a lot to be desired.
Hope you have better luck.
