This winter we left our traveling 5'ver behind, and only used the truck and the old disposable 5'ver (which is stored south) during this winter's snowbird season.
FWIW;
I can fix an RV better then most techs. I just don't want to do it anymore. It's a PITA.
Buying an expensive RV's is a good way of losing money, and should only be done if you can afford the lost.
Right now I'm in a casino hotel room costing $40/night with free breakfast buffet overlooking 30-50 RV's that are dry camping. It was 95f and very sunny here. I would hate to be in one of those tin cans. DW and I sat by the hotel pool, soaked in the hot tub, then returned to our air conditioned room for our soon to start happy hour.
I went from deep south Texas to the boarder of California mostly along I10. A lot of 90 degree hot days, and mile after mile of "no" and "where". Glad I was in the truck and not putting up with the stress of having a RV along that route.
Got 2,000 miles left to go to get back home through desert and mountains. We both want to be back now, and will be driving hard. I would hate to have to be driving an RV right now. It's one thing to drive one handed, and another to have two hands on the wheel with white knuckles. Maybe that very expensive MH that you want might be the ticket (doubt it.)
Forums are great places for people to forget their everyday woes and dream about a carefree lifestyle. Once you have true RV miles under your belt you learn RV reality is not so carefree or glamorous as the blogs would make it appear. Who would blog about the **** that goes with the lifestyle. The whole purpose of a blog is to make others think you got it all going on.
Enjoy your beach house. Try not to look back. Have fun on the cruise, your rig would have depreciated almost that much in a couple of years or less so think of it as being a free going away present.
