Now go back to scale with same stuff in TV, your rear axle will be somewhere in the 1,000 lbs lighter. Front axle maybe several hundred pounds heavier.
Add both differences to your trailer axle wt.s, now you have the real trailer wts.
With all that weight added to rear axle, the front gets lighter. Hope not to much lighter.
The scales at least at DOT scales will be correct within 200lbs plus or minus. I would bet CAT are the same. They are made for really much heavier vehicles and 200 lb one way or another is nothing for a 105,000 lb truck/trailer.
I have no idea how, who or when CAT scales are certified. DOTs as I recall every 6 months. I had to have that information for each court case.
