We have and they have tried to fix this without a finding a work around. I would like to make them buy it back but outside of proving they sold us a truck that was not compliant with NFPA/Code standards I might not be able to.
Well don't think you need cruise control??? Disable it
This is all I found,,, And NFPA is not my second language,:::

16.10.1 General Provisions.
Provisions shall be made for placing the pump drive system in operation using controls and switches that are identified and within convenient reach of the operator.

A.16.10.1.2
Pumps are operated from the side, top, front, or rear of the vehicle, and stationary pumping requires that no power is applied to the wheels during pumping. Therefore, it is essential that any controls that could apply power to the wheels while pumping be equipped with a means to prevent dislocation of the control from its set position in the pumping mode.
16.10.1.4
Where the pump is driven by the chassis engine and automatic transmission through a split shaft PTO, an interlock system shall be provided to prevent the pump drive system from being shifted out of the “pump engaged” pumping mode of operation when the chassis transmission is in pump gear.
16.10.1.5
Where the power train from engine to pump includes auxiliary braking devices, they shall be automatically disengaged for pumping operations.
