Thanks guys, glad everyone is liking it. Now to answer a few questions. The left and right lower sides and the middle section was made from styrofoam packing pieces that were in my attic. The upper left and right sections were made from sheet styrofoam. I cut everything out with a razor knife and sculpted everything with my hands/fingernails and only in a few places used a wooden skewer. The plaster is regular dry wall joint compound thinned with water so it doesn't go on too thick. Also when it dries it cracks really nicely due to all the water evaporating so it leaves a nice rocky look. Clint you are right I now have a few more cargo bins that can mount onto the Big Mother Trucker. Now I am off to finish painting the storage rack and prime the walls, maybe another update tonight or tomorrow.
Oh yea, as for the transport all I want to do is fabricate the seating, a platform on the back with controls for a driver and paint it. I was thinking about sticking with black, what do you think about the color of it?
