I would say as far a deuce front axles go, yes on the capacity being close to being maxed out with a front winch, I have to disagree on the 5t front axles, these axles were used on everything, cranes, grade alls, drill rigs, and other heavy front loads, if these can not be used as a brush fire truck, someone had better tell ALL the water truck owners or the loggers, these guys will over load to just before the breaking point. These axles were used every day in the CIVI world back when these trucks were first designed (39 series), since the axles ARE THE SAME in the 809 and the 939 series trucks, these WERE the heavy duty front axle of the day, I really do not see to much to worry about, my front axle survived a very hard landing when I got my m819 wings, so hard that my front motor mount about got ripped from the front gear cover.
