Took my brand new 310 GK and 3500 ram dually to i the cat scales today: I use an Anderson hitch and with the trailer on the front axle weight was 140 pounds less than the truck with no trailer. I think this is because I have the coupling block in front of the fifth pin. Do I need to be concerned do you think? I like the Anderson. Lots of turning space so don’t want to rotate the coupler if not needed
