Just wanted to share our roof raise! 12" roof raise on our 2011 Chevy Express 4500.
Below the window raise along with raising the doorway so I don't hit my head every time I leave the bus
I have a few square tubes welded in the hat channels but I also currently have some hat channels being made that will be welded into place. Ignore the fender dents, they'll be addressed once I go to paint.
I am working on a video that I'll post whenever I'm finished with the raise.
