If you wanted to build a custom show truck, there are no rules. I'm not sure of the rules on drag trucks, racing trucks or tractor pullers, but that might be an option as well.I don't know how things are in Canada, but in North Carolina, we have been known to build all kinds of configurations in the 1:1 that serve no real purpose other than looking cool. I had considered this myself, but have too many other irons in the fire. So, go for it! I would really like to see this build come to pass! I have the engine if you need one.
