I owned a 1948 Willy’s truck and yes it will carry one ton of material. Both trucks are under powered, with the Willy’s being ridiculously so. As we all know, flat ground is ok, but on highways on hills, both trucks struggle and require lower gears.
The Willy’s had respectable spring packs for the intended payload and a beefy split rear end made by the Timken bearing company. Axle housing split just off center with pinion gear/bearings mounting as part of housing. No gear adjustment, just separate, replace parts and assemble together, fairly simple. This rear end was used up into the early 50’s when Chrysler began using the Spicer 44 rear end. Unlike the Dodge, the Willy’s had no other payload rating other than highway, but was the same for on/off road.
The real comparison of the trucks comes from what they can carry off road and the grade ability they can pull. As you can see, the Dodge can haul a considerable amount more and negotiate a 24% steeper grade. I’m not sure what the 4x4 trucks today could perform considering payload and grade ability, but the Willy’s and Dodge were designed for Ranch and Farm work mainly. Being under powered for the road probably was not a concern since these trucks experienced more off-road activity.
