We get these covers every few years, and since our tongue jack is covered 24/365, one will last a couple of years before it shows sign of peeling. That one then goes on the jack throughout the winter months, and a new one goes on in the spring for the next camping season. They may last longer if I was to treat them with protectant, but I'm not that fussy about them. These do hold up to being on the jack while towing the trailer, which is more than I can say for one other brand we tried. These are great for the price, and are heavy duty in comparison, will fit most jack heads with room to spare. The cinch cord and sliding spring clasp are robust and outlast the cover itself. We do put a small plastic bag on the jack head first just for added rain protection. Our jack (Bulldog 4000 lb model) is too expensive not to take every precaution we can. We do recommend these covers.
