Another opinion:
About nine years ago DH & I bought a 2005 5th wheel RV (in great condition) and a 2004 diesel Silverado 2500 Duramax with Allison transmission to haul it - both still going strong. Occasional repairs, yes. But that's true of houses and all vehicles.
Setup takes about an hour, as does the close up when it's time to pack up from a campground and hit the road for the next one or to go home.
Pluses: we bring along a familiar, comfortable king-sized bed and bathroom including step in shower, fully stocked kitchen and pantry (no worries about what to do with leftover food when it's time to move on), and clothing for all weather from bathing suits to rain gear to heavy jackets and gloves, not just a suitcase or two. And we aren't repeatedly unpacking and repacking over the course of our trips.
Nice campgrounds with full hookups average $80 per night. As for the crowds, I've never consistently run into a friendlier, more helpful group than while at campgrounds. They come from all over and are happy to sit with a cup of coffee (or a beer) and shoot the breeze for half an hour - or to just say "Hi - how long are you here for? If you need anything, just give me a shout!" From then on we wave hello and goodbye and watch out for each other - as good neighbors do.
Very true that while towing the RV our gas mileage drops to roughly 10-11 mpg. Once we unhitch the RV we use the truck for exploring, shopping, whatever.
I'm not suggesting anyone run out and buy and RV, merely pointing out their advantages when traveling around. I know several people who sold or drastically downsized their homes and live happily in their RVs much of the year.
@bobcat48, whatever you decide, I wish you well.
