D-Tub Base Vehicle

The D-tub is built onto a 1988 Chevy 3500 crew-cab, long bed, dually truck.  It was formerly used for hauling, but the engine died so I got it for cheap.  I ripped out everything not needed in an electric vehicle, like the engine, transmission, exhaust pipes, axle, etc., saving lots of weight and making room for the D tub parts.

The truck came with a 7' x 9' flatbed, which I stripped down to use as a frame to build the stairs, decking and shower onto.  I've ended up mostly cutting apart the flatbed frame, but it was very useful when trying to visualize where all the parts would go and how they would fit together.

The rear seat was removed to make room for plumbing, and the tub ingresses into the cab 14" for weight balance and space reasons.

The suspension is currently stock, but that might change depending on how it rides.  I might remove the overload spring if it is never used, just for weight savings.

I'd like to put in air bags to adjust the ride height depending on the load.  That way, if 10 people jump on, should be able to adjust the tilt of the vehicle so that the water is level across the tub.
