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?
I'm sure that the mysteries of Max Tow will be revealed someday. I've not seen any answers yet.
