The carefree awning on my new camper has no adjustment and goes pretty much straight out. As I read through a few posts with people with the same problem I'm wondering if I can just change the shock to a shorter one to let awning pitch more? I was side by side with a friends camper that has the same awning. Everything measures the same except for the fact that his shock is 18 inches and mine is 23 inches.. Any input would be awesome..
