I'm a tree lopper, so my ba tradesman povert pack work ute has copped a significant beating repeatedly. The most I had was 2200kg of logs. The crane driver thought it was going to collapse. The diff welded itself up that day. If it had a manual it would have killed the clutch. In my bf xr6t ute the most I have had is the weight of my toolbox, climbing gear, saws etc. so about 150-200kg
