Welcome to the forum.
Somewhat like you, after years of traveling via Motorcycle and tenting it, these old bones needed some creature comforts.
Our choice was the XT 276, a 30 foot unit. We looked at a 21' footer but the wife is claustrophobic so that was totally out.
Very pleased with our selection.
