Have you seen the
Happier Camper? Small, molded fiberglass, totally modular and user-configurable interior, and a rear hatch. Made in CA.
Also,
WeisCraft makes a small trailer in CO.
I had an Aliner Ranger 12 for 1 year. I didn't feel like it was such great quality (mine was 4 years old when I bought it, and several minor problems were showing up during my ownership). Stooping to get everything becomes tiresome; there is no upper cabinetry so you bend over to reach every single thing you want, and even the countertop was too low for me. I actually got no better MPG towing the Aliner than I do with a molded fiberglass trailer like my Li'l Hauley (cargo edition of the Lil Snoozy). And I always worried about how I'd handle things if I had to set up or take down the Aliner in a strong wind. Some folks love their A frames, but it wasn't for me.
