Our nephew out west is getting married next summer and we're considering taking a 2 week vacation, renting a class B, and using that experience to determine if we would want to own a class B RV. There's a 2006 PW Plateau TS available. If I go check it out this month, what should I ask the owner to help improve our chances of having a good 3,500 mile vacation? BTW, I'm not a 100% total RV novice, my dad had a 33' Airstream/Thor class A for 15 years and I once rented a class C from Cruise America for a long weekend. Thanks!
