Midship entrance door question
So I've been considering moving my front door away from the front of the bus to the middle, I think my Floorplan has the perfect opening for it. And that way I could have a passenger seat beside me when I'm driving as well! I know there are a few threads already on this topic, and I have looked them over. There is just 1 more question I have left that's unanswered from what I can find.
I plan on using a basic rv door. If the space between the ribs of my bus are 29 inches, around the rv door be 29 inches or 27/28 to allow for a frame or anything?
