The 1993 Ford Ranger was a pickup truck owned by Hank for almost 20 years, and as result he was quite emotionally attached to it. Bobby was attached to the truck as well. He traded in the Ford Maverick he owned for it. Peggy loved the truck despite having previously threatened to divorce him if he ever got the rid of the Maverick. The Ranger is red and it has the dashboard and interior of a 1993-94 Ranger, the grill occasionally appears as a 95'-97' feature, this may have been an aftermarket part added by Hank, possibly due to the stock grill being damaged.
In the Season 5 episode Chasing Bobby, the truck was retconned from a 1993-1994 model to a 1986 model. In previous episodes, the truck was shown to have an automatic transmission, but in Chasing Bobby it had a manual transmission. Some earlier episodes show the truck as having a floor shifter, while others show it with a column shifter. The truck is depicted as not having 4-wheel drive. Since the Hills live in Texas, it can be assumed that Hank's truck has air-conditioning. In some episodes, it depicted as as having power windows, while others show it with manual/crank windows.
There are numerous goofs with the truck in Chasing Bobby, including the truck being depicted as 20 years old. The episode was made and took place in 2001 and while the Ranger did make its debut in 1982, extended cab models like Hank's were not introduced until 1986. Hank's Ford ranger can be identified as a 1986 model because it has an extended cab, which was not made until 86'. And because the engine still has a carburetor, which was a feature discontinued by ford adding fuel injection in 1987 and the following years on for the vehicle.
It started having mechanical problems and breaking down repeatedly in Chasing Bobby. Hank refuses to accept it after the mechanic claims it only has 500 miles left. Hank did everything possible to save her including buying new parts and tuning up the engine. Despite everything the transmission was shot, engine mounts were rusted, and the engine kept catching on fire. Bobby attempted to help having his dad take it to a shop called Pick-Up Truck Heaven but it turned out to be a car dealership. During the trip to and back the truck kept backfiring and finally died for good on a train track. Hank tried to fix it but it wouldn't start and the truck was destroyed by an oncoming train. Bobby later finds the gear shift knob near the location of the truck's destruction and tells his dad that maybe she died on the tracks as it accepted it was finished and told Hank to move on and get a new truck. Hank finally accepted his old truck is gone and bought the 1999 Ford F-250 Super Duty from Pick Up Truck Heaven. To honor the memory of his old truck, Hank keeps the Ranger's gear shift knob in place of the new one which happened to also have a manual transmission.
