I've only taken 2 trips with my 21SS but after TRYING to take the cover off with the bunk ends open while it was sitting in the driveway, I decided that removing the cover BEFORE opening the bunk ends would become part of my regular set up routine. So I take it off when setting up & stash it under the Roo. Then put it back on as soon as I get hitched up to leave.
