In a nutshell-$80,000 should buy you a pretty nice 5er. Add in another $50,000-60,000 for a TV and you're talking some real money, and that's not cheap.
I think the experience should concentrate more on what you need. For instance, if you plan on parking in an RV resort, then don't buy something with top-rated suspension and a leveling system. Instead look for nice interiors and good HVAC and a winterizing package. But if you plan on dragging it all over the countryside then you will probably need that suspension and a top-drawer TV as well. There are lots of different models in different price ranges and I would recommend that you try to attend an RV show and see 'em all, but don't get sucked in by a salesman until you have finished your homework and know what you need and want.
