Many folks who tow their cars "four down," without using a trailer or tow dolly also use a speedometer disconnect system. After all, when it comes time to sell the "toad," who wants to how high mileage that really isn't "drive" miles, but mostly a lot of "tow" miles. But there's a bit of a drawback.

Without the benefit of a firm odometer reading, it may be possible to miss out on vehicle maintenance schedules. No, when the engine on the toad isn't running, it's not racking up maintenance issues that are handled via oil changes and lube jobs. But even if the engine is off while you're towing, "the wheels on the bus [still] go round and round." Yep, if you're not keeping up with tire rotations, it can cost you dearly.
So here's the deal: It's important to keep track of how many miles your tires have traveled. Some RVers find keeping a logbook in the cab of the motorhome, and jotting down miles traveled with the toad behind, then adding the miles from the toad's odometer, will give them a good handle on when to rotate tires. Rotating your toad tires every 5,000 miles can help even-out wear issues between the tires.
