We could swap, I'm a solo RVer (less you count Kitty and Katty my feline traveling companions) and live in a 38 footer :)
No,,, I think I'll keep this multiple 2-way radio equipped rig, too much work to move the radios to a new "house", too much custom mounting work done.
Seriously I am surprised they are telling you "Too small" I mean wha'ts up with that? Snob city it appears.
You need what you need, and a 25 foot can fit in campgrounds where a 30 footer can not even turn the corner.
