We have a 2013 Flagstaff pup. We’ve been having a little trouble with the electric lift the last few times, but it always ended up working. Today my husband and son are camping and the lift motor kept grinding. The top would go up, then drop a little. At first he couldn’t get the door to position, because it wouldn’t stay in the right spot. He put the support braces up and went to the hardware store to get some boards to support the opposite corners. The motor kept grinding & he came back to the lift motor pulled under the trailer. Any suggestions welcome!
