Jeep Gladiator J300/3000
First introduced in 1962, the Gladiator designations were J200 (short wheelbase trucks, up to mid 1965); J2000; J300 (long wheelbase trucks, up to mid 1965); J3000; and J4000, the first model with the longer 131-inch (3,300 mm) wheelbase.
Gladiators were available in RWD and 4WD, and came either with a solid front axle, or independent front suspension with optional dual rear wheels.
Gladiator trucks were available in the following configurations: Cab and Chassis; Wrecker; Stake Bed; and chassis-mounted campers with extended wheelbases. (See the Dually Registry listed in the links below for more information).
Gladiator bed variations were: Townside, Thriftside (a “step-side”), and Stake Bed.
The Gladiator name was dropped after 1971, after which the line was known simply as the Jeep pickup. The pickups were designated as J2000 and J4000 models until 1973, then J10 and J20 models from 1974 to 1988. https://jeep.fandom.com/wiki/Jeep_Gladiator_(Original)

The J-Series trucks were offered in two- or four-wheel drive in two main lines: the 120-inch wheelbase J-200 and the 126-inch J-300 series. Each of those divisions offered a range of GVWRs from a half- to one-ton. In the J-200 line were 4,000, 5,600, 6,600, and 8,600-pound GVWRs. The J-300 line started a little higher with choices of 5,000, 6,600, 7,600, and 8,600 pounds. Both the 8,600 pounders were duallys (models J-230 and J-330). Once past the choice of wheelbase and GVWR, buyers selected between the old-style Thriftside, the flush-sided Townside, or a platform/platform-stake bed. Bed lengths ranged from a nominal 7-footer on the J-200 to an 8-plus footer on the J-300. The duallys were offered from the factory only with a platform bed, but a cab and chassis truck could mount any of hundreds of aftermarket be
