New to site and to owning a travel trailer

So, hello all. Wife and I picked up a trailer back in September that is in a seasonal campground so it will not see asphalt. As we moved in, we found some substantial water damage and found most of the living room and tip out was completely rotted out. Previous owners did a great job hiding the damage. Anyways, will have a ton of questions and issues to toss around here. Pressing question is I have a line on a brand new awning roller with canvas, was told it is an Addeco brand, trailer came with an old awning that's pretty trashed, looks to be a Dometic, I am curious if those arms will work with the new roller.

Also have tons of pics of the remodel so far, where can these be posted?
