buying 2007 Winnebago View - what to look for

Hi! I've been a previous travel trailer owner (unfortunately it was totaled in a hail storm a couple of years ago), and decided to change to a motorhome with my next purchase. My partner and I found a good deal on a 2007 Winnebago View with low mileage. According to the dealer, it was owned by an elderly couple who kept it garaged and just traded for something else. I know these stories can be b.s., but from the photos, it does appear to be in excellent condition. I don't see that they really changed or upgraded anything, as all of the standard package items are there (and look unused). We fly down to pick it up in a few days. The dealer is adding a new set of tires and will do a full inspection and fill all fluids, etc. They won't be doing anything else, *as a courtesy* based on the price that we were able to talk them down to....so I really want to make sure we check everything out before driving off. What else should we be aware of to watch for upon pick up? I have read that the generator might need new oil, and that we need to be aware of the turbo hose issue. Anything else that is a MUST?? Thanks in advance!
