I purchased one from Andy (Inland RV) a couple of years back. The attachment for the awning was already on there from a past awning. You will need two people when you slide the awning into the groove. Other than that, installation was easy. Just read the directions, walk it through. Most people with average mechanical skill can do it easily. I have been happy with mine.
When you first install the awning snug down everything but do not tighten too much, after everything is in place, give it a trial open & close....then - one at a time remove each screw and put lock-tight on it then tighten it down to stay.
I recommend you invest in a set of ball bungees for tie down back ups.
It really is a straight forward type of project.
