I bought an off-brand full security encloser like the Tuffy unit. Still in the box. Unknown quality.
I like the idea of always having with me at a minimum, my recovery bag.
Do you have a link? I've been considering something like this, but don't want to spend a fortune not knowing if I'll stick with it. Right now I have to accommodate a small sub enclosure in addition to what I'd throw in the security enclosure, and also hoping to leave room for the pup to ride on top.
