Odd. Our piston only allows the door to open 90 degrees. Yours allows more movement than that?
Some people with the LCI doors, me included, have installed the supplemental Lippert "friction hinge" kit. That kit adds a couple more hinges that have a lot of resistance in them. While I still have the piston in place to avoid any awning arm interference probems on the rare occasions when we open that awning, the friction hinges keep the door where I put it, even against the pressure of the piston.
They also keep the door from slamming open if "someone" just lets go of the door or if the wind partially closes the door momentarily.

Note that some people have said their newer entry doors do not have enough room for the friction hinge kit. Our 2020 GT5 34H5 had plenty of room. The friction hinges are the same size as the other hinges already installed.
