We purchased this 2008 Grand Junction last Fall with the intention of fixing it up, making it our own, so to speak. We decided to replace the roof membrane as the first chapter. I organized myself last Fall, getting together all the materials & planning my approach. The wood used is actually for my master bedroom renovation in my home here, but it’s first duty was to be used for scaffolding ! The frame under the front cap was to support the cap as it has to be rotated forward at the top in order to tuck the EPDM membrane under it…conversely at the rear, the rubber goes on top of the cap, these two different install methods prevent rain etc., from being forced under the caps during travel. If the members or yourself are interested in the roof replacement, I can post pics & text from start to finish.
