I am in the process of designing my bus. I am looking for ruff dimensions of a 40ft rear engine with a handicap door. I would like to get the width. Floor Length from engine wall to wheel well, wheel well to wheel well, wheel well to the driver seat. And the location of the HC door.
If you give me your bus dimensions I would be glad to start an image file on SketchUp, Free 3d sketch. So people can start designing the project.
