Look at the a pillar on yer truck. that is all that counts.
Soo many options, different configurations no way the internet can keep up.
BUT the MOT, DOT, Weights and Measures Guys only read the numbers on the a-pillar on yer truck.
Nothing else counts.
Payload is deceiving, GVWR is the term to pay attention to..... and scale yer truck fully loaded, people, gas, dogs, water, clothing...
Fully loaded as you leave town scale it..... best way to find out if yer legal.
After an accident if the DOT guy thinks you might be heavy....
They will scale it.
