Hi, we were in a similar position. I had posted about debating between a Casita
a few weeks ago, and we actually ended up with an Escape 17A! I think the Armadillo
Backpack was our first choice, simply based on how it looks--much more modern, loved the color choices, lighter weight
. My 3 young kids loved the idea of a triple bunk. The used Escape happened to be for sale
and in a city where it could be shipped up easily to us. And most importantly, it was available NOW (versus the 6 month wait for building a Backpack). So, we decided to go for it. We just got it a few days ago, and we've enjoyed hanging out in it in our driveway.
My kids are small, so the 5 of us fit in it fine for now. Can't wait to take it out!
There's a small FB group of Armadillo and Backpack owners that you can join to get a better feel for them. Definitely more limited than Escape, but seems like a happy bunch of folks. One of the more recent builds included a HUGE bed (king size, for a trailer), an overhead bunk, an enclosed toilet (not sure if it is a wet bath), and front kitchen with window.
Enjoy the research process!
