I don't have access to a scale or this would be easy. Trying to center a 3520 onto an 18 foot flatbed so that the tandems are taking most of the load but still have enough going to the truck to keep everything stable. I know that there should be 10-15% of the loaded trailer weight on the tongue. I guess what I'm asking is has anyone weighed a 30xx series tractor with FEL and something like a RB to know how much each axle is supporting? With all the snow around I'm not going to take it for a ride on the trailer to see what feels the best.
