In the meantime, that's what I will do. But I we like to take the sofa's out and set them up under the awning/tarp at our destination. When your partying with 10 - 20 people, it keeps all the traffic and dirt from inside. I also like to keep the front 1/2 of the bus open as my multi-purpose area. This way I can adapt to any need that arises: floor space for extra bodies, bike/dirtbike hauler, construction materials, moving truck, etc...
I have checked around or called a dozen or so boneyards in my area with no luck. I think a Bluebird rear door has less of an angle that would require less flattening, but I sure would like to skip that extra work. Putting in this door will be my first cut & weld project, so I want it to go as smooth asa possible.
