Comfort? Most RTT's are going to have a marginal mattress, at best. I've put a Thermarest Camprest on top of mine to help out, and will eventually replace the Thermarest with a Megamat. But most offer decent comfort from the elements. We augmented cold weather performance with an $8 sheet of Dow styrofoam insulation with incredibly good results, plus the added benefit of making it a bit cooler in hot weather. Also added a Ryobi battery powered fan for hot weather. And our Smittybilt RTT came with LED lights. Just some of the things we did to improve our comfort level. So my point being, ANY RTT you get will require some tweeking in the comfort department. Look at features, quality, price point of a tent...to see which one speaks to you.
