Very rural wide open state with many ranches that trucked water around . They had/have a farm/fire/military endorsement. I drove an F900 with 2000 gallons of water and air brakes no CDL. It clearly meets the tanker and B requirements.
They allowed the operation of vehicles with higher gross weights than 16/10/26,000 as long as it didn't exceed "on the scales now" 16/10/26,000 . The book gross of the F600 is 18,999 with 9,999 towing max combined GVW on our old B160 IHC was 29,999 right on the door post next to the 193 BHP @4400 RPM . It sounded like it was going to start swapping holes over 3,000 whether it was push or pull .....
