If all goes well, this will be a link to Dan's bus:
And you guys realize you need to pay me royalties, right?
On mine, I took only a small wedge out of the frame, because I wanted to have enough frame left for a stout trailer hitch, and also not lose any ground clearance. Come to think of it, I did not even cut an actual wedge out, but simply cut a slot, and then forced the upper part down over the lower like the blades of a pair of scissors. Not building a watch here!
I also notched the crossmembers that are part of the floor so that the surface of the floor is all the way down on the frame at the rear.
Happy New Year!
