Good choice on the Access brand cover!
I finally replaced an Access roll-up cover that I had on my Chevy C30 after about 15 years of constantly sitting in the sun and taking every bit of weather during that period. It was convenient to use, looked great, and lasted for 15 years! The heavy gauge vinyl was still in reasonable shape, but my wife had purchased a new cover for me years ago (not an Access ) so I went ahead and changed it out.
The new cover looks fine, but it's a bit flimsy, and I know it will never hold up as well as the Access.
I have a Volkswagen, with a non-standard luggage compartment, could not find a suitable tonneau in any way. I`ve bought a cheap cover - and very soon became sad with it, looking for a good Access now. Do not be greedy, it is better to buy an expensive and good thing than being disappointed with cheap stuff.
I have found the best solution for myself. Using MIG welder welded laths on the inside of the body on which subsequently stretched custom-made awning made of rubberized dense fabric. Thus it is impossible to be groomed with dimensions and the tent is ideal.
