I know a lot of people here don't approve of this method, but my dad and I raised the roof of my Thomas bus by 24" at the windows. He welded in 1x2 tubes in the hat channels with 1" angle iron on either side for the sheet metal rivets. We overcame the 6-degree bend by replacing all the upper sheet metal and the way we welded in the replacement hat channels.
A few reasons why we raised 24":
1. I wanted to replace the windows with dual-pane ones, so we didn't need to worry about putting the windows back.
2. I was going to do a 20" raise, but decided to raise it 24", we wouldn't have to cut the sheet metal down.
3. We decided to put the water tanks inside the bus floor to heat/cool them easier. I want a lot of water for boondocking, so I have two 100 gal freshwater tanks. We are going to raise the floor of the bus to cover the tanks so they don't interfere with the layout, and the rest of the extra space will be for running the electrical conduit, plumbing, or floor storage.
Got pics? That's a lot of geometry change, I'd love to see how it came out.
The place I get steel will cut it to size for nothing. I'd hate to base my geometry around stock sizes of plate!
