- Pickup trucks continue to be registered by the unladen weight and assessed a weight fee regardless of the vehicle’s GVW. The unladen weight of a pickup cannot exceed 8,000 pounds and its GVW rating must be less than 11,500 pounds.

If you got these numbers right both trucks require cvra, but if one had 7900 curb weight and gvw 11400 it would not require it. Notice in the text they discuss pickups separately from "commercial vehicles", they have separate rules for all pickups in general. I know it sounds conflicting because first they say "regardless of GVW" and right below they say just this:
Exception: A REG 4008 is not required for pickups with an unladen weight of 8,000 pounds or less.
But seems like they had capped cvra exemption by GVW 11,500 for a puckup and it's published here
AB-2963 that would have exempt all pickups from commercial fees had failed to advance
