I think you get what you pay for. I bought a suitcase for my 95 foot F350 Crew Cab Long Bed Single Rear Wheel which is my restoration project and is too big for the garage. This coating was only needed to keep the truck dry while I finished the body work. I didn't expect this cover to be great but just hoped it would last a few years until the truck was fully painted and then fitted with an expensive cover. The case worked well initially, but quickly fell apart. Tears at the seams and becomes brittle after a few months. Customer service was great and sent me a new one when my original broke after the gorilla tape was able to fix more after a year but unfortunately after about a year with a replacement and the same problems with frequent breaks and breaks. Initially it is very waterproof, but over time it loses this property. I'd say it's still 96% waterproof, it's lost water resistance in all the places I don't care as it can't get into the cabin where it's leaking. I'm sure this case would be fine for infrequent outdoor use and indoor storage when not in use or just regular indoor use, but for regular outdoor use it doesn't hold up too well. I'm in Pennsylvania so summers are hot and winters are cold and we get average rainfall.
