Hi all general question. What is the real world bed hauling capacity on an m925a2 truck on paved roads. I recently hauled 8.9 tons of Gravel. The truck overall did great with the exception of a wicked 6% grade. I'm relatively new to these trucks and I'd just like to know the real capacity on these trucks. The springs only dropped two inches! Given a proper hitch what can these trucks tow before the tranny gets angry? Thanks, my son wants to put the top down to buy some milk!
