Example:
2016 CC Longbed 4X2 DRW 6.4L 3:73
GVWR -----13,300
Payload ----6320
RAWR -------9750
YET 'SAE J2807 Compliant' max tow rating is ONLY 12,450# (20%=2490 pin weight)
Not going to run out of payload, not going to run out of rear axle (or tires w/dually), not going to run out of GVWR
But run out of GCVWR which is 19,900
Same truck w/4:10 diff
GVWR goes up 700# (14,000)
Payload goes up 700# (7020)
RAWR same (9750)
BUT max tow goes up 3500# (SAE J2807 Compliant)
and GCVWR goes up same 3500 (23,400)
SO with 3:73 rear diff........NO
with 4:10 rear diff......YES no problems
