Just curious, do you have a basement? I am setting up my 525 XL right now as well and am wondering if I need to be looking at supporting the rafters in the basement. Mine is going to be against a foundation wall so I'm a little less concerned, but just curious as to your situation.
Just re-reading some posts and realized you are setting up a 525xl now as well! That’s awesome! Do you have a build thread? If so, please share! If not, start one!
