One other thing, i know power equipment tends to emit a gasoline odor, and will you be carrying gasoline cans in the box truck?
Thanks, very important point.
The plan is to store fuel in tanks mounted to the frame (under the box). There will be fuel in the equipment however which will necessitate a roof vent to let any fumes escape. I agree that there should also be no door or opening to the cab.
Two potential downsides I see to the cabover box truck.
1. If you had to haul much debris from a jobsite (something like stinky grass clippings)
2. Having your nice expensive beautiful advertising on the sides getting scraped up by tree limbs. Is there a paint or material that doesnt get scrached up?
