Interesting product here and this provided some ideas. Thank you.
The problem with camper doorways is that you are going in and out all the time, especially if you are cooking outside. Granted this product opens with a tap of the foot on the bottom bar but I just can't see myself closing it back up 30 times in a day. I wonder if the dogs would be clever enough to nose it open and walk out too.
I knew this would be an interesting problem. I'm even going as far as thinking that I might have to buy a one-piece Coleman camper door, the whole assembly (probably at several hundred dollars) and mounting that frame with velcro or snaps of some sort. Then the door will be on a good frame and hinge, snap shut when closed and be very sturdy. Yes, it'll have to be dismounted upon closing the 2720SD.
In thinking of an alternative, the problem with a sliding door is that the TrailManor has a very uneven wall by several inches. Plus I would have to put a small track on the floor which would not be the worse thing but something to trip over.
