Hi I have a 2018 377 Vengeance Toy Hauler, While at the dealer for a warranty issue it had a leak on the top of the jack at the front of the 6 point leveling system. The rv slowly dropped to the ground. If I were at the campground I would not be able to hook up. Does anybody have any suggestions how I could safe guard against not being able to lift the rv if this happens again. Is there something I can install.
