The ramp idea looks like a feasible method and should work perfect. Did you do anything to reinforce the bus roof metal or just go with it as is? I was thinking of putting in square metal tube but that may not allow the roof metal to conform if I did that ahead of installing the units. Before I do anything, I need to figure out what roof paint/sealant is best that would not allow dirt pickup.

I reinforced the roof with two considerations:
I spanned across the ribs using a 16g patch, 28.5"x30", a healthy overlap for the 24"sq hole, room for two beads of Dynatron. Also, secured using 64 rivets, 40 of which are center of the ribs.
I then repurposed the factory ehatch supports, which also span across two ribs each. For these I tightened the spacing to match the wood frame. While it was temporarily clamped flush/square with the hole, I marked/drilled the ribs, & doubled the number of screws used to support the factory hatch.
I also left a 3/16" gap between the steel supports and roof skin. Only the wood is squeezed tight to the roof & AC. The steel supports the wood, & indirectly the roof. PL Loktite S30 between the wood & roof.
