This sounds interesting...
But a couple of questions;

How would you get consistent weight for traction on every participants truck?
A box holding a predetermined weight that hooks into the truck's 5th wheel?

And what about a consistent height pulling hitch for every participant?
Something that clips onto the rear of the frame, or rear Xmember?

Not everyone showing up at a show will have their truck set up for pulling...
Having a truck weight box and pulling hitch assembly along with the sled will allow anyone to participate.

Just my thoughts.
