Based on recommendations by friends (hi Bill) we chose to have our base plate installed by Eyers Hitch of Santa Clara.
We asked them to:
- Install a Roadmaster Baseplate
- Install the Brake Buddy breakaway switch.
- Route and install the battery disconnect switch since they were going through the firewall anyway
- Install a battery trickle charger driven by the tow vehicle.
- Install the diodes that allows the tow vehicle (the motorhome) to drive the tail, brake and turn signals on the car.
Eyers did a wonderful job. That is basically the long and the short of that.
For the initial test run, we went up to the local university where we hitched up for the first time and drove around the lot with one of us in the passengers seat of the Smart. There we learned the value of bungeeing the steering wheel - otherwise you get a violent side to side steering wheel oscillation when making turns. We learned that most Smart tow-ers bungee the steering wheel.
Since then having the Smart under tow has been a total non-event - other than having to retrain the Smart transmission when we unhook.
The choice of a Smart, was, we think, a good one. The car is so light, we don't even know it's there when we are towing.
