1st question. I have a 94 f-450/pwrstk with a grain body dump How many Tons of stone do you think I can get in this truck? the job calls for 10-15 tons of stone to be graded into an existing driveway which has been damaged by run-off water. Is this to much to do by hand(2 people) or would renting a bob cat be a better Idea? Any input would be greatly appreciated!
