Val and Earl use the truck
1965 Jeep Gladiator J200 while working as handy men in and around Perfection. The side of the truck reads 'V. E. Odd Jobs'. And they used this truck when they first tried to leave the valley. When forced to turn around due to a rock slide, presumably made by Graboids, a Graboid grabs the rear axle with its tongue. They didn't realize this at the time and thought they were simply hung up. The finally broke free and when they got back to town discovered the tongue, thought at first to be the entire creature.
Earl owns the truck and uses it on his ostrich ranch. The side of the truck now read 'Earl’s Ranch'. He and Grady drive it to Mexico after being hired to hunt Graboids that were terrorizing an oil field there. While there it was outfitted with a seismo monitor and they used it in their hunt for the Graboids. When a Graboid jumped out of the ground right in front of them Earl put the truck in reverse to try to get away but ran it into a ditch and broke the axle and had to call for help. While on his way to rescue Earl and Grady Pedro was attacked by Shriekers.
After Tremors 2: Aftershocks
It is unknown what has become of their truck though it is presumed that Earl and Kate still own it.
