Weighed at CAT scale - Need some clarification

First, congratulations on taking a trip to the scales. I am one who likes to be under GVWR on both truck and trailer. If you need to tweak your loading by shifting 150-200 pounds from rear to front, or the other way around to stay under your ratings, I think you are too close to your maximums. As noted, not even all the vehicle manufacturers agree on the amount of front axle weight restoration.
