trailer was hooked up.
Generally you want 13 percent of the trailer weight on the tongue and 20 percent of the tongue weight is redistributed to the trailer axles via a WDH. Working backwards thru the math with the little info given gives a trailer weight of around 8600-8700 pounds. Add another 75-100 pounds for the WDH. That would give you a tongue weight of around 1100+/- pounds. Your truck weighs around 6100 pounds without the tongue, around 7100-7200 pounds with the trailer attached. Based on the numbers provided, you are under your trucks gross of 8800.
Why not weigh the truck without the trailer and get some solo truck only numbers? That way you can determine if you are unloading too much weight off your front axle.
