I never thought about the exhaust fumes coming off my power washer as well as my air compressor. Both of the units sit back from the rear door.
When I started up my AC unit fumes all over the place.
I thought made I would have to get a generator to sit outside the truck to power a box fan that I could place in the front of the box and blow the fumes out the rear.
Also was wondering about rigging some type of tailpipe assembly that I could attach to the Honda motors and pipe it thru the side walls of the truck.
Get a exhaust fan and put it on top of the truck and run it off your battery.
great idea! or rig your pressure washer and compressors so the exhaust is right at the back of the truck.. our compressor blows right out the back.. its about 1 foot from the end of the box truck...
I got an exhaust flex pipe from the local napa store. using some sheet metal screws attached it to exhaust. the ran it out the floor. drilled a whole with a hole saw bit. works great now no smell. in my other truck also did the fan in the ceiling(attic fan for house) solar powered!!!
