First, I assembled my materials.
Then I drank an adult beverage by a company called Abita (not a requirement, but sure tasted good).
Then I knocked out this:

All in styrene. Side sills are 0.010 x 0.156 styrene; end sills are 0.010 x 0.100 and the deck is v-groove to simulate wood.
Looking at it critically, its too short by about 2 or 3 feet. I guestimated its length at 18 feet from the size of the trucks relative to the whole package, but I think I need to go a tad longer. It also needs to ride a hair lower, and the side sills aren't as pointy as they need to be. On the other hand, the IMRC 33" wheels look great in the trucks, and they roll really well.
And yes friends, that's Atlas Tru-Truck the critter is riding on.
Off to work, coffee, and more noodling. Stay tuned.
