Thinking about throwing a RTT on my 4runner. I haven't slept in a tent in years though because my back just doesn't do well on the ground. Are the mattresses in these RTTs any good? Has anyone thrown a memory foam topper on one? Is there room for that? Thanks for any input!
Tons of info in the RTT section http://www.expeditionportal.com/forum/forums/138-Roof-Top-Tents-and-Awnings
