Overbrook makes a lot of good points as the asking price is on the high end of what I would want to pay for a 1995.
I will add to his handling advisory however: I know that (at least with the Ford chassis) in 1995 they had a narrower wheelbase and smaller rims. You can see from the pictures how the front tires are set in a bit from the fenders. It should track right at highway speeds and with the tag axle, the push/pull from Semi Trucks etc shouldn't be too bad but be aware there will be some wander to it even when it was brand new.
I believe that is the model M-J and just under 38' in length. It does appear to be fully loaded at least from the outside. Every awning has the metal covers, there is a backup camera and a SWEEEET mural painted on the back. I like the air horn! Like others have said, looking at the exterior and the owner's grounds my gut feeling is that it is going to be in great shape. You still have to be diligent in inspecting it of course.
I have no idea if that is the ford or Chevy chassis from the pictures. Crawl underneath and look for dripping fluids as Overbrook said. If it is Ford, specifically look just behind the transmission at the parking brake assembly. Be aware that if it is wet or dripping, it could be a sign of big trouble. It only holds a few ounces of ATF for lube and cooling. If it was run dry, the shaft overheats and deforms into the splines on the transmission output shaft.
Oh, if you want to look at the interior, here is a link to a dealer selling the same model.

And here is a page where you can download the manual. Just scroll down for 1995.

It looks like a good floor plan for not having a slide. As far as driving something that big: Just like everyone says, it's not that big of a deal. You just have to be aware of what's going on around you and how far the back hangs out behind the wheels.
