After TNT was bought out by the United States Hot Rod Association in 1991, the show began primarily airing the Pendaliner Monster Truck Series and NMRO mud races held at Special Events' 4-Wheel and Off-Road Jamborees. A frequent feature of these shows was a highlight segment of "Tough Truck" amateur off-road races near the end of the monster truck episodes. The final season of Trucks and Tractor Power had Gary Lee as the host at the Monster Truck Thunder Drags, with Dave Rief, and later Tom Rivers, for the Jamborees.
