We had Jayco's version of the Ailiner for one season. We absolutely loved it. Awesome to tow, easy to back-up, tons of storage for a pop-up, and yes, easy and fast to set up. I am 5'8, so i never found there to be a height issue. We had the one without the shower/toilet,but that was ok, gave us the big bed. Sitting at the dinette was never an issue, beause the 2 domes in the front are there for window, and head room purposes. The A-frame concept is awesome, you have to try one to appreciate what they were made to do. You dont need a TT to get the conveniences you want, the A-frames have it in a smaller, easier, lighter package!
