The biggest reason people have trouble setting up/tearing down and/or with the door is stuff is out of adjustment, either due to use over time or the TM has severe issues... My 2007 3326 was a fight to set up, and the door never worked right (it stuck so bad my wife said it was a fire hazard). I had TM replace both roof shells (roofs were sagging), torsion bars, and lift arms so all moving parts were new and aligned properly. I can now open that 3326 with one hand and the door works perfectly.

Point being, I’m guessing a new one that is set up properly will work a whole lot better than a 15-20 year old unit that is probably all out of whack.
