Below are a few of the vehicles I've built in the last 3 decades.
Wildmman Wheelin Lo Step Van
This is my current prone driving position step van.
I built hand controls and a driving platform with
a sub-woofer box inside. It has a rotating art gallery in
the front and motorhome ammenities in the rear. It
also has a mega-sound system, solar panels, A/C, and
a super quiet generator. The floors and walls are
composite plywood and insulation board. This van took
2 years to build.
