Consider a B+ or C motorhome. On my Blackhills trip last August, I stopped at the Horseshoe Casino in Council Bluffs IA for the night and the tiny, wiry woman next to me in Sprinter 3500 Road Trek was having trouble getting the power cord plugged into the twist lock on the vehicle end. (bent blade, I straightened it with needle nose pliers) Anyhow, she told me her husband had died and she had no desire to drive their 40 ft motorhome, but wanted to travel, so she sold the motorhome and bought the Road Trek. She was headed off to see relatives in Missouri when I saw her.
I tell this story to offer options. A Road Trek, an Airstream (yes I know, $$$) or a Phoenix Cruiser or similar would be a great touring vehicle, and much easier than depending on a relative or having to park a trailer yourself.
