The last time I weighed in the trailer axles came in at 8150. The rest of the weight sits on the truck as tongue weight of 1450.
That gets me just under the the rated axle combined weight of 8800 and just under the 9680 Gross trailer weight. I was thinking originally that the axles should exceed the combined trailer weight but I was not taking into account the tongue weight.
Good thing I only carry one bike or I would have to leave the beer at home...
