Tire Rotation for Towed Vehicles

[redbaron73]

I tow a Jeep behind my motorhome. The jeep odometer does not change when being towed. I have to manually track the additional miles on the tires to do the rotation on a proper schedule.

The way I do this today is an excel spreadsheet that has a date, odometer of jeep, and then another column for addl tow miles.
I add an entry at the end of each trip to reflect the miles towed that need to be added to the odometer to show tire age

Would like a way to track additional usage that is not affecting the odometer. This might also be useful for trailers that do not have odometer or hour meters.
