Can anyone confirm or deny if a digital tachometer/speedometer registers the driven (towed) miles on a toad - with the engine off obviously.

None of mine have ever registered towed miles.

When we first towed our Suburban it registered towed miles, even with the key out. When we subsequently had it in a dealership for an unrelated dash issue, I asked if there was a way to prevent towed mileage recording. I don't know what the dealer did, but it subsequently didn't record mileage when towed behind our motohome. By then, the Burb had racked up over 10,000 towed miles

Answer varies car to car, however on the ones where it does,,,,, Usually a fuse disables it. you can remove the fuse, install a simple adapter (Cost about 50 bucks can make one for way less) and put the fuse back in (the adapter) instant on/off switch.

As far as my Dodge goes as long as the key is off the odometer and everything else is off so no clocking of miles.
