    Actually, adding tongue weight to trailer GVWR is normal and correct. Using only axle ratings results in GAWR. This is an air-braked trailer, and very few if any air braked trucks would care at all about 6000 lbs tongue weight unless the hitch was on a long over-hang behind the wheels.

    I am not getting on my soapbox here, but 10% tongue weight is the minimum for the trailer to handle well, not the optimum. This is one major reason heavy trucks handle heavy trailers much more safely than pickups do.

    Hey Georgia Iron, I picked up the tank and valve locally at Woodwards Spring Shop in New Bedford, MA.

    The tank was labeled as "Air Tank 9.5" dual" and is similar to this tank;

    The valve was labeled as "valve KN 30400" and looks to be similar to this valve;

    Thanks for the comment.

    No problem.

    It should be pointed out that this valve is for the old style trailers with NO SPRING BRAKES.
