I am on my third cover for my 30' fifthwheel. I use pool noddles on the sides of the rear ladder to prevent rubbing, on the rear corner I made a cardboard cover for the corner (reinforced with duct tape) and dropped a sand bag on top. Same with the Digital TV antenna. I also use sand bags to protect the edges of the rubber roof from the cover rubbing during windy days and the front cap, corners. You can use plastic grocery bags filled with sand. Need to replace the bag each season as they will fall apart. This has worked for me and it only takes a few minutes to put out before unrolling the cover. I keep my cover on the garage roof with all of the bags. Parked 4" away form the eve of the roof and it's easier than hauling it up a ladder. Good luck.
