Looking at a 2005 Windsport 35D... questions

Hi, we are looking at possibly buying our first RV. A 2005 Windsport 35D, Workhorse chasis with 11,000 miles. It's with the 2nd owners, between them and the first owner it's only been used 7 times. The Onan generator has 208 hours on it. We did a quick walk through of it and everything looks like new inside. The only issue I could see is the awnings are faded and stained along with some of the lamination having issues, and there's a little fading and cracking on the decals on one side of it (sun) but it'd probably liven up with a good waxing. The window cauking by the gasket also looks a little faded/cracked. It's got new tires and a new roof. It also just got it's state inspection sticker. The current owner says it has a GMC motor but I've been trying to do research on it on the web and everything keeps saying a Ford V-10? There's been no mods done to it by either owner other than a CB radio antenna. What type of things should we be looking for/at? We are going to take a more in depth look at it next week or so. We're also thinking of possibly finding a mobile RV repair guy to take a look at it. Neither of us knows much about RVing other than our parents, mine owned a 5th wheel and hers a Class A. The current asking price is $35K. The TV's and backup camera would have to be changed/updated along with the lights (not sure how big/bad a job that would be to do).

Thanks for any advice.
