Thanks, I used the 1/8" angle and it is surprisingly rigid, I'm able to stand on it without it bending and it is pretty light. This is the second iteration of this solution, the first one I used a 1/16" thick 1/2" wide aluminium angle and I was able to bend it. Good thing about doing it this way it that if I find I need to, it would be easy to change it to steel. I think I will end up adding a hasp just for long term storage when I won't be able to check on it as frequently as I can now. Eventually I hope to replace the door with a RV door.
Thanks. My initial budget was $14K, I know that I am over that by at least 3 or 4K. I kinda don't care at this point.
I set up a separate bank account and everything I bought for the bus came out of it so I could go back and figure it out to the penny. Maybe I'll use that as historical data when I do my second bus.
