About the quality of your intended RV? That also is really a c r a p - shoot too. There's the good, the bad, and the ugly. And all 3 RVs can be standing beside each other on the assembly line. Best advise to offer here is ... when you take delivery of your RV, leave no stone unturned. Make the dealership PROVE to you the camper is sound. Even have them pull the slides out and get a garden hose with a sprayer and spray the seals and see if water makes it past to the inside. In this day and age, this is your best line of defense... and if there are any problems with the camper ... be prepared to walk away from it and not feel pressured into taking something inferior to your expectations.
Seconding that!!!
