LVTR1 was the recovery and maintenance variant of the LVTP5. A 60,000lb (27,000kg) winch was installed, and the power for this was provided by a Willys 4 cylinder 48hp engine from the M38A1 quarter-ton truck. A boom was mounted on the front of the vehicle to assist in removing engines or other loads, and the crew chief acted as the crane operator. The boom had a capacity of 8000lbs (3600kg) with a single line or 14,000lbs (6400kg) with a two-part line. A General Electric welder was fitted, which could also be used as a battery charger or assist with cold-weather starts. A 5 ft³/min (.14m³/min) air compressor was also installed.
Modifications to the LVTR1's engine air intake and exhaust system produced the LVTR1A1. The most obvious external difference was a large housing on the vehicle's rear roof above the engine.
