Large fivers are bigger in interior space than motorhomes. I can detach.
I will wait on the full roof solar panels that can even charge in the dark and run all items with 70K furnace and oven, even at once. In effect - propane no longer needed. Odorless tech sewer systems that decompose and evaporates waste from the underbelly or sides. In effect - dumping the tank is no longer needed. Soundless generators that go 10 weeks on 1 gallon of gas or water. Insulation that won't freeze water even with the solar energy off, eliminating winterizing. Never really needing to do anything with your rv - all year.
All you need to do with the rig is... just add water.
This will be someday. Not soon, but someday.
My sis chose a gently used beautiful 2010 Carriage. It's her decision. No argument from me.
Thanks all.
