Yeah, I guess you can build with plywood in a more or less desert environment.

The required clearing of drain holes with hot wire, the sanding of all mating surfaces before gluing them up, the corrosion problems with fasteners, the way mice seem to always find their way into them, and the damage that spilled grease, oil, and fuel cause, these are all construction details which make plywood a most annoying material to work with in vehicles. On the plus side, it dents less, takes paint better than aluminum or steel, and an argument can be made for the use of renewable materials.

I like it.

Presumably they recruited Female drivers who had experience as magician's assistant?
Experience of sawing the lady in half would appear to be necessary.
I've always liked the idea of plywood construction for vehicles.
My plywood golf trolley certainly stood up well and was easy to repair when necessary.
