When we bought our first RV (a popup), brand spanking new in 2000, we absolutely loved the dealership we went with. The sales force was top notch in every way.
Then, when we started needing warrantee work done, we had to deal with the service component of the dealership. They were like night and day different from the sales people. Totally incompetent in every way. For the next several years every time we had service issues it was a total nightmare.
Moral of the story: before you plunk down your hard-earned cash, examine the reputation of the service component of the dealership. They are the ones that count. They are the ones you'll be dealing with long term.
