Well I too wonder why you are in MI and your towed in TX.
Assuming one of the following:
1: You had to tow something OTHER than the car back to MI with the motor home.
2: Motor Home damaged beyond repair and you returned to MI via plane, train or bus.
3: Some other good reason.
Auto Driveway is option one.. option 2 (Which is what I suggest this time of year) is return to TX with motor home, Wait for warmer weather and tow it back.
But seriously, Option 2 is mostly a joke. Cause if you could do that, you'd be doing it.
