My little bro had a mid to late 70s (I think) Jimmy PU with a 454 and 2-4s that would scoot that horse trailer down the highway with two 1200+ lb horses in it like it wasn't even back there. That was back when we were making one roping during the Rodeo and 2 slack ropings after the show in 3 different towns in one night. "poor horses" and "lucky us" - no hijack intended
