2016 Nissan Frontier flat tow

I tow a 2WD 2009 4-cyl 5-speed and another OP here just got a 2016 V6 6-speed, don't know if his is 2WD or 4x4. The 4x4, manual transmission, is to be towed with the Transfer Case in 2WD High Range. That essentially makes the 4x4 a 2WD. Then the manual transmission is placed in Neutral for being towed. The Frontier transfer case doesn't have a Neutral position, so the Automatic 4x4 can't be towed such as many can.

With manual transmission, Nissan has no speed limit for towing, but would like the engine idled in neutral (clutch engaged) every few hundred miles.
