Will the F-250 rack up miles being flat towed?

I have a F-250 Lariat 4X4, electronic shift, automatic, push button start. Just wondering if it racks up miles while being flat towed. This place is a wealth of knowledge. Thanks in advance

Wouldn’t think so if the engine isn’t running.

It isn't supposed to be flat towed. You'll have to disconnect the drive shafts to flat tow it.

From the owner's manual:

If your vehicle becomes inoperable
(without access to wheel dollies,
car-hauling trailer, or flatbed transport
vehicle), it can be flat-towed (all wheels
on the ground, regardless of the powertrain
and transmission configuration) under the
following conditions:
• Your vehicle is facing forward for
towing in a forward direction.
• Place the transmission in neutral (N).
If you cannot move the transmission
into neutral (N), you may need to
override it. See Transmission (page
205).
• Maximum speed is 35 mph (56 km/h).
• Maximum distance is 50 mi (80 km).
In other words, you have to really, really, really need to flat tow your truck to do it. There is further instructions in the manual on how to flat tow but it says to put the ESOF transfer case in neutral. Mine has no such setting, but it does say to do this:

Four-wheel-down Towing
1. Put the ignition in the on position, but
do not start the engine. If your vehicle
has an ignition key, turn the key to on.
If your vehicle has intelligent access,
press the engine START/STOP button
once without pressing the brake pedal.
2. Press and hold the brake pedal.
3. Rotate the four-wheel drive switch to
2H.
4. Shift the transmission to neutral (N).
5. Rotate the four-wheel drive switch
from 2H to 4L and back to 2H five
times within seven seconds.
Note: If completed successfully, the
information display shows a message
indicating that your vehicle is safe to tow
with all wheels on the ground.
Note: If you do not see the message in the
display, you must perform the procedure
again from the beginning.
Note: You may hear an audible noise as the
transfer case shifts into its neutral position.
This is normal.
6. Leave the transmission in neutral (N)
and turn the ignition as far as it will go
toward the off position (it will not turn
fully off when the transmission is in
neutral). If your vehicle has an ignition
key, you must leave the key in the
ignition while towing. To lock and
unlock your vehicle, use the keyless
entry keypad or extra set of keys. If your
vehicle has intelligent access, press the
engine START/STOP button once
without pressing the brake pedal. You
do not need to leave your keys in the
vehicle. You can lock and unlock your
vehicle as you normally do.
7. Release the brake pedal.
Note: Failing to put the transfer case in its
neutral position while towing with all four
wheels on the ground will damage vehicle
components.
Note: You can check four-wheel-down
towing status at any time by opening the
driver's door or turning the ignition to the
accessory or on position and verifying a
message displays in the cluster.
To exit four-wheel-down towing and return
the transfer case to its 2H position:
1. With your vehicle still properly secured
to the tow vehicle, put the ignition in
the on position, but do not start the
engine. If your vehicle has an ignition
key, switch the key to on. If your vehicle
has intelligent access, press the engine
START/STOP button once without
pressing the brake pedal.
2. Press and hold the brake pedal.
3. Shift the transmission out of neutral
(N) and into any other gear.
4. Release the brake pedal.
5. Apply the parking brake and disconnect
the vehicle from the tow vehicle.
6. Release the parking brake, start the
engine and shift the transmission to
drive (D) to make sure the transfer
case is out of neutral (N).
7. If the transfer case does not
successfully shift out of neutral (N),
set the parking brake until you can have
your vehicle serviced.

Thanks for the replies. It can be flat towed. It's in the owner's manual under recreational towing.

The question is.......

Does it rack up miles while being flat towed?

I don't have a definitive answer, but my guess is no. Modern vehicles uses electronic speedometers. No longer is there a mechanical cable connecting the speedometer to the transmission. If the ignition is off the odometer should not operate.

It sounds like the running gear will rack up miles regardless if it shows on the odometer or not.

This. If the ECU isn't powered the system can't see the VSS signal and thus can't log the mileage.

Exclamation

I would think that a related issue would be braking the free-wheeling flat-towed truck. Specifically, does the tow vehicle have the braking capability to stop both it and the flat-towed truck (6K lbs.? 7K lbs.? 8K lbs.?), at speed, going downhill, and/or repeatedly?

HTH,
Jim / crewzer

I'd think that you'd have to install a supplemental braking system like they talk about towards the end of this article.

I have also been wanting to know if other on this site have flat towed these new super duty.
I have a tag axle RV with plenty of towing power & yes it would have a brake system installed in the truck.
Has anyone on this site done this?

I personally would not tow a vehicle with an automatic transmission with the drive wheels on the ground unless the driveshaft was disconnected. Automatic transmissions do not have a roller bearing where where the driveshaft connects. Typically they use a plain bearing that needs oil. With the engine off, the transmission pump is not being operated and not circulating transmission fluid. Some manufacturers allow for limited speed and distance on flat towing. But I would only flat tow if I had no other choice.
