Why can’t this vehicle be flat towed? I am surprised that this is not available .
It would be another option to be towed behind an RV

The transfer case does not have a neutral position. Unlike the classic Defender and mo

The user manual warns you not to flat tow it any real distance.
I'm learning to being more aware about how old my knowledge is, but most autos don't have a rear oil pump just one in the front driven by the engine via the torque converter. The engine needs to be running to make oil pressure for transmission cooling, cleaning, lubrication and control. Towing an auto any significant distance or at speed with the transmission output shaft being driven by the drivetrain will do damage to the transmission due to a lack of oil pressure.
Caveat: I cannot confirm if the ZF8HPx series has a rear oil pump.

The Grenadier has the neutral stop bolt in the transfer case to isolate the auto transmission from the drivetrain (and circumvent the auto trans parking pawl if the vehicle is inoperable), but I'm of the opinion this method is only so the vehicle can be recovered onto a flatbed trailer hence the warning in the owner's manual.
