Gypsy, I would stay away from pop-ups unless you intend to stay put in one place for quite some time. The set up and tear down can be a hassle. Some of my friends, shorter women like myself, have a difficult time getting the door in place. If you have to tear down in the rain, things get wet, and you need to pop back up soon to let the fabric dry.

RV Sue's blog. It's a woman (in her 60s) and her dogs full-timing in a 17' Casita with full solar set-up. It's my favorite blog of all time!
She gives a ton of useful information.
Good luck on finding the trailer that's right for you!
