LVT2's cab was placed a small distance from the bow, and the cab had two windows for the crew. LVT2, known as Water Buffalo, had a cargo capacity of 5940lbs (2690kg), and incorporated torsilastic suspension. This suspension involved springing the road wheels on rubber springs. The track of LVT2 was made up of two chains, each with a pitch of 4" (10cm), which were attached to each other by steel crossbars and the large propellor-like grousers. LVT2 also used the engine and transmission of the gasoline-powered light tank M3.

LVT(A)2 was an LVT2 with the 10- and 14-gauge steel on the cab front and rear, hull front, and pontoon sides replaced with armor plate. The armored cab was fitted with a roof with two hatches equipped with periscopes, and there was a single observation panel in the left front side of the cab that the driver could open for direct vision. The additional weight brought on by the armor reduced the LVT(A)2's cargo capacity to 4950lbs (2250kg).

LVT4 was a remodeled LVT2, where the engine was moved from the rear of the vehicle to behind the driver's cab, yielding a larger cargo area and allowing a rear loading ramp to be installed. Applique armor could be attached to the LVT4: .5" (1.3cm) armor on the front and .25" (.64cm) on the sides, but this reduced the LVT4's payload by 3000lbs (1360kg). The LVT4's cab had two large glass windows and two roof hatches, and three armored cabs could be installed as well, with .5" (1.3cm) armor to the front and .25" (.64cm) armor on the top and sides. The front panel of the early cab was solid, with the driver's hatch on the front plate opening outward for observation (much like LVT(A)2's). A periscope was installed in each roof hatch, and these were originally covered by a plastic hemisphere, but these plastic covers were eliminated later. Later armored cabs were fitted with a ball-mounted .30cal machine gun at the assistant driver's position, and the final armored cabs had the ball-mounted MG as well as vision blocks for the driver and assistant driver in place of the driver's earlier vision panel. This final version also lacked the driver's periscope.
