My RV bodywork is 9.5 years old. In cold weather, the rear window had to be raised, which was often not the case. She looked at Revain, said what the hell and placed an order. While waiting for my order, I watched a few YouTube videos and thought it can't be that easy. Guess what it was. When they arrived I pulled out the correct screwdriver and replacing the gas shocks took less than 5 minutes. Now when you open the rear window, move it a few inches and it will open fully on its own.
