To remedy this, I cut two lengths of nylon cord long enough to go up one side of the RV, across the top and down the other side. Then, I punctured two tennis balls and ran one end of a cord through each of them. I tied nylon washers (to protect the cover) on the end of the cord threaded through each tennis ball to keep it from pulling out, and a metal split key ring on the other end of each of the cords.
Now, when I need to get into the coach, I attach a split key ring to the loop in each zipper pull, pull the zipper up to take out any slack in the bottom of the cover, step back and throw the tennis ball over and across the top to the other side of the RV. I can then pull the cords down from the other side until they stop and the zipper is pulled all the way to the top (being careful not to wear grooves in the cover material). This allows full access for entry through the door. Once I’m done I simply reverse the process.
To keep the cords from tangling during storage, I wrap them tightly around opposite sides of an electrical cord wrap and push the tennis balls through the center.
