Some prototype truck stuff

The main purpose behind making the prototypes was to find out how about I'm going to make the thing work (wheels spinning, steering, speed, motion paths, suspension, weight, cogs, trailers).

I went down the manual animation route after first planning on using dynamics after a few talks with Pat Imrie. Things seem to be working OK with work progressing into making the trailers work with the opening sides and massive tree pinging out of it.
