Sincere question: why would using an RTT increase the likelihood of stuff being stolen? Seems to me that with a ground tent, you are leaving even MORE behind to be stolen when you drive away for an outing away from camp. Is it because a tent-less camp looks potentially abandoned? Perhaps because a prospective thief who sees a tent would be concerned that someone was IN the tent? If that's it, any thief can quickly and easily confirm that a tent is empty w/o raising suspicions.I plan on avoiding official campgrounds as well but do still worry about not having a site to come back to, or stolen stuff, with a RTT. I mean time wise to pack up and stuff is a non-issue for me. The set up we have now is longer and more involved by far than what a RTT set up would be.
I like the idea of being off the ground though especially with any off the beaten path camping just for the animals alone. So much to think about haha!
