We also love our older RV, a '94 Winnebago Brave. Paid $10K cash and was able to use it on trips the weekend after we bought it. I too feel like I'm traveling in unbelievable luxury every time we use it as it does everything we need it too and we don't have to spend time at the factory getting anything fixed. A little preventative maintenance when we got it has gone along way.
Every time I wake up in a toasty warm RV and get to use my own personal bathroom without having to dash to a campground one I can't believe how lucky I am! In addition the seats are super comfy, the mattress is top quality foam, the original refrigerator cools like a champ and has no recalls on it and there is no out-gassing of formaldehyde because it out-gassed a long time ago. To top it off we fit in all the great national parks and don't mind a bit if a branch scratches the side because there is no paint job to show every little mark.
We also have loads of cargo carrying capacity (no granite or tile to take up the weight), the RV drives straight and true (no heavy slide on one side to throw everything off) and we don't get thrown around by the trucks (were narrow body and non-basement so have a lower center of gravity).
We don't have fancy tvs or satellite dishes but then again I don't watch TV at home so can't really see taking up the habit on a camping vacation.
