We also have the shock that keeps the door at 90 degrees on our Passport 2910. Main reason it is there is beacause if not, the door would hit the awening arm. The shock is practicle for when your going in and out often, but when we are put and in the TT, I hate not having a full view out of the door. I've checked and the shock comes off real easy (10 seconds with a flat head screwdriver) so I will be installing a latch ( between 7" and 12", depending what I find) so I can leave the door open as far as possible without hitting the awening arm.
...I want my cake and eat it too!!!
