I did the same thing with the bed slides on my 2017 model but was lucky enough to catch if before it tore. Now it has a scuff as opposed to a tear. The best way I’ve found to fold it up is to drop it about halfway with all the poles out and slide in. Then pull all the canvas out so as not to damage it. On mine though I also need to be careful of where the wiring sits as well. Trial and error I guess. Also had an issue with the canopy separating from the top because of the jacks not right enough letting the whole camper “twist” when inside after setup. I usually set it all up. Inside and out. Then tighten the jacks again to make sure nothing has adjusted. Great functional camper though. Happy camping.
Couple of notes. My mistake was using my stabilizer jacks as leveling devices. This is a No-No; which I've since learned. There are many ways to level the camper side to side, but using the stabilizer jacks is a recipe for disaster. Also, the bed rails on this camper come into each other upon fold down, and veer away from each other side to side; this is why they are prone to catching canvas that is in the way. The King beds are great, but due to the immense size, you have to be cautious about making sure they aren't catching upon closing the unit up.
