I have an SS1500 which is the biggest and heaviest of the soft side pop ups.
Mine is a 2014-15 model with the RT electric roof lift and solid one piece door and I have to honestly say, I have had absolutely no issues with mine, nothing. I use mine primarily for off road camping (seasonal access and fire roads on a 1 ton 4x4 diesel pickup.
Nothing has broken, nothing has quit, nothing has fallen apart and it don't leak anywhere either.
I did change all the outside lights to LED's and added the backup wireless camera. I also installed a 1000 watt PSW inverter and a second house battery.
The RT electric roof works flawlessly just like everything else and fit and finish are first rate. The units are much, much improved over the older Palomino's with the crank up top and the 2 piece leaky rear door.
Your only issue will be getting in and out. I would suggest a set of scissors steps. With the short door, it can be a head bumper climbing in and getting out.
I would just buy one new for what a new one costs, it's a pretty good bargain in TC's today.
My 2 cents
