So you just want a comfortable place to sit? Something like a couple of big recliners should do it. Now what about a dry vs wet bath. Certainly a dry bath would be better. While you are at it look at the kitchen for convenience. Do you want nice wide countertops, an oven, a microwave, a large refrigerator? While you are at it you might want to upsize just a bit more so you have your own laundry.
This is how people start out with huge RVs. Ask any RV salesman. They will help with a process. I have no idea what is right for you. I can only tell you my wife and I resisted the tendency to go big and years later are still happy with the decision. We went full time, along with our 2 cats, in a 9 1/2 foot Northstar Igloo. Our recliners were a couple of zero gravity chairs which hooked onto a bracket on the rear ladder. Years later we even traded them in for light weight folding aluminum chairs. With a small size and a couple of solar panels, we did not need RV parks or equivalent sized campgrounds. We did not tow tens of thousands of pounds of stuff so we traveled a lot and stayed in National Park, national forest and often BLM dispersed camping areas.
Years later we are no longer full timers, but often travel for months. The current trip started in NY in the beginning of August and so far has included: Badlands NP, Big Horn Mts, Yellowstone, Glacier, Olympic NP and the Washington, Oregon and Northern California coasts, then Great Basin NP, Bryce, Capitol Reef, Natural Bridges, Monument Valley, Canyonlands, Arches, and lots and lots of places in between. You can imagine, I don't sit all that much. I would rather travel instead of towing a recliner.
Your plan has lots of merit, although good weather and limited bugs would make that more doable!! : )
