I'm still waiting to find out if it currently has any active functions while the vehicle is not in tow mode. Max Tow is now a $1000 option. I'd buy it and did.
My point about the unknowns of Max Tow has nothing to do with towing, only as to what conditions the separate Max Tow A/C compressor and battery coolant circuit engages. It could easily be software locked to engage only when needed and when the truck is in Tow Mode. Or, it could cool your battery without using tow mode on a hot day, completely separately from your cabin A/C. Does this affect range when the cabin compressor would work adequately, as it does in trucks without Max Tow? When the Max Tow compressor engages, do both compressors always operate together? Also, it could engage while DCFC, without using your cabin A/C compressor at all. Does it?cooling is cooling, there is no relationship as to whether the truck is in 'tow mode' or not
