First a little explanation of the procedure.
The 4th window back would be removed and an opening would be cut out of the of the side of the bus. And about 2 feet of the floor. Then a box would have to be assembled to house the stairs. A door would need to be constructed and fit.
Meanwhile, up front the door would be removed, a metal frame would be constructed on the side wall and at floor level. The floor would be finished like the rest of the floor and the side wall of the bus would need to be enclosed. Hopefully, the metal cut from the siding of the bus at the new entrance would be enough to cover the old opening, and the window would be able to be reused for the passenger side.
This would in no way jeopardize the structural integrity of the bus.
This would not impact the bathroom area already planned.
After painting, the change would not be recognizable.
It can be done. Check out SportyRicks bus
