This article is from the The Monster Truck FAQ, by Jeff Hawkins with numerous contributions by others.
A. Dan Patrick, of Patrick Racing Enterprises, Inc., specializes in
Monster Truck frames and chassis components. Patrick, who also
owns the SAMSON Monster Truck, was instrumental in designing and
building the first ever tubular chassis on Bigfoot 8 back in 1989.
At a recent event I attended, every truck there but one sported a
Dan Patrick frame. One of the trucks was completely built by Dan
for a owner/driver client.
