The other day I decided to draw a trailer that resembled the one we had when I was a kid.  The brand of trailer we owned was a Serro Scotty.  You can pick out a Serro Scotty by locating the super cool upside down nike swooshish  wheel well.  I was also thinking about incorporating this design into some of my future t-shirt plans.  It was fun busting out a real technical type drawing again.  That's kind of where my artisitic roots are from.
