Wow, I thought having a truck mean't I would get to compete in the "truck class" with everyone else who has a truck. Kinda makes the playing field level. I also thought the extended cab of a pickup was the storage area inside the cab. Very little options for transporting anything inside a p/u. Hearing that I will have to compete against hatch's kinda throws cold water on this for me.
I won't nag anybody about it though, the contest is the OP's idea and his rules apply. I might build it though and have it metered, then sell it to some local SPL kids.
