Hello to all! I recently pulled the trigger on a 99 international 4700 5 speed manual dump truck with the T444e motor. I didn’t do as much research as I should have. I put 9000lb of shell in the bed and it fell flat on its face, had to slip the clutch a little to get her to move. I guess my question is, how much can I tow with this truck? I know it’s a high rpm motor but would be nice for a little bottom end instead of giving her a push with the excavator bucket. I appreciate anybody willing to help . I can’t find any numbers on towing pounds, have a lot of hilly terrain in my area.
