to be in use by National Guard units as late as the mid-2000s. In order to replace its 1950s vintage M135 fleet, the Canadian Army adopted licensed versions of the M35 (and M36 variant) built in Canada by Bombardier in 1982. As of 2020, the trucks, designated MLVW (Medium Logistics Vehicle, Wheeled) were still in service although limited spare part supplies forced the fleet managers to cannibalize from selected donors. Canadian vehicles feature a hard cab roof, an adjustable driver's seat, an Allison MT-643 automatic transmission, a Detroit Diesel engine displacing 500 cubic inches (8.2 L), six wheels instead of ten (using single wheels on the tandem rear axles instead of dual wheels), and an ether-start for winter operations. The original 11.00X20 bias ply tires on split ring wheels were later changed fleet-wide to Michelin radials on bolt-together wheels in 2002 due to safety concerns. Canada had been investigating a replacement under the Medium Support Vehicle System Project, and a vehicle has been selected. The MLVWs were initially not deployed with Canadian Forces in Afghanistan because of their lack of armor protection. An armor kit was subsequently developed leading to a limited deployment of the vehicles. Variants The M34/M35 series of trucks came in wide array of variants and subvariants. As noted engine differences could be noted by the A1, A2, or A3 suffix, but additional suffix letters were also sometimes added. These letters had different meanings depending on what variant to which they were applied. Under the nomenclature system used by the United States Army Ordnance Corps Supply Catalog (known as G-series) the M34/M35/M36 family is designated G742. Cargo As noted the original basic gasoline-powered truck variants were first the M34, and then the M35. An extra long wheel-base variant, designated the M36, was also developed (featuring a cargo bed). Variants with a C suffix (such as M35A2C or M36A2C) featured a straight drop-side cargo bed. M44, M45, and M46 simply designated the long single tandem, long double tandem, and extra long double tandem chassis for the M35 -ton series of trucks; there was also a short tandem chassis without an M designation. These cab/chassis would serve as the basis for many more specialized variants. In 1982, Bombardier produced a M35 variant for the Canadian Forces' medium logistic vehicle, wheeled platform. This featured an Allison MT-643 automatic transmission, and a Detroit Diesel engine displacing 500 cubic inches (8.2 L).
