Look into lubing the lift system and pullies. Lift systems require regular maintenance and lubing as it can pick up grime etc. Best rule of thumb is to lube it every camping season. I like to do it in the spring as I discovered critters, bugs, like the nooks and crannies under the camper while it sits over winter. Unfortunately I do not have your type of lift system so can't help with the how to.Boy, I’m surprised. It was a real bear to go up.. came down easy. I’ll get under it and see if there is another issue.
Thanks for the quick reply.
