I hope I don't get kicked off the forum for this, but have you checked out the Trailmanor line ?? The 2619 or 2720 (not SL or SD models) would sleep 6, no canvas, and tows great since they folds down. We had a 2720, but had to give it up because of the wife's bad back....the fridge and much of the storage is down low, and the beds are high.
The other big drawback is they are expensive new !! We were lucky to find a great used 2720 when we bought.
