Cool Towing 4 wheels down-odometer runs

Have set up my 2018 Lariat PowerStroke Diesel 4WD with wheels down, tow-able capability, however on first tows, the odometer keeps running despite passive 4 wheels down. What gives, should be free-wheeling. Why am I getting accumulated miles on engine and vehicle when it is being towed? Planning on a cross-country tow behind motor home. Could add 5k excess miles.

the output shaft (and rear driveshaft) is still rotating even with the truck in neutral.

You'd need to unplug the transmission output speed sensor and retest

Thanks. Seems weird as I have towed Jeep Liberty wheels down without added miles.

You are are saying the sensor for odometer is rearward of transfer case and transmission, therefore cannot be uncoupled by simply the drivetrain disconnect engineered to tow 4 wheels down. Page 310 of owners manual.

Your help is greatly appreciated.

Sounds normal to me.

I would hope it will still continue to track mileage with the engine shut off. No different than driving it.

Not to go on a long story, but one of my friends bought a car that was towed for a long time behind a motorhome, but didn't find out until after he purchased it.

So the car should've had an extra 30k+ miles on it according to the original owner. Especially with the suspension and tire wear, it was quite evident something wasn't right.

If you don't want to put miles on it, then I suggest getting a flatbed equipment hauler.

Also, it's one thing for a tow truck to haul something, even with 2 wheels on the ground, because that is typically short distance. I'm referring to long distances, like cross country, where the mileage could significantly impact the condition of the vehicle, like hauling it behind a motorhome on 4 wheels.

Respectfully disagree,
Mileage should reflect engine service and transmission, both of which are unused during this towing. Tires are parts expected to wear, and replace. Shocks and struts are nominal expense to replace and expected to wear out over time. Mileage again, should reflect engine and transmission as my experience says, having driven vehicles over a million miles. Would like an option to avoid adding artificial miles to the engine and transmission that do not reflect it's actual service.
