All it takes to make it true is to rephrase "rear axle"
with "both truck axles weight"
And if you change "My crowd was bigger!" to "My crowd was smaller" can make it a true statement.
But CAT scales usually have 200 lb jumps so that will bring big error margin.
I have used Cat scales 100s, if not 1000s of times. Every one rounded to 20 lbs.
Why not use bathroom scale with lever board?
Wait, that would bring us back to 4th grade physics, ... or was it algebra?
A lever and scale can do the job, but to get within 20 lbs you would need to be sure you are weigh at same hieght as tow, and must make sure board and tongue ride on points, not flats.
