I think that generally they are measured from ball to back bumper, but in recent years I have seen where they measured the box so you just have find out the actual measurement that you want.

CD is correct. Most TT is measured ball to bumper while fifth wheels are measured by inside box measurement. No idea why

Actually they have changed how they measure 5th wheels now. They are measured from the King pin(tront) to the rear bumper(rear). Here in Oregon they want all the money they can get so the longer it is the more you get charged for plates.
