New trailer, two weeks old. I noticed that when closing the awning the front arm does not go tight to the trailer before the rear side stops tightly. It is the Lippert Solera awning and the motor is on the rear arm. I read a bunch of posts and am sure that it is straight and the fabric doesn't walk one way or the other when closing. It just seems like it's longer at the front than the back. Anybody have a cure?
