I'm towing a '13 Fiesta, but have only towed about 800 miles so far, with no issues. Just follow the flat tow procedures in your owners manual. I printed up a copy of them and keep it on my sun visor so I always have the set up procedure handy. Be sure you disconnect the negative battery cable as your last step. I had a battery disconnect added at the battery, so it's just a flip of the switch to disconnect.
I'm using the SMI Stay-In-Play aux. brake system and had the LED toad brake indicator run to the dash in the MH. The installer had some issues with the correct wiring procedure since the toad battery has to be disconnected, but he called SMI and got their "work around" wiring info. No problems at all with the system. Just flip a switch when you're ready to tow.
Blue Ox tow bar and base plates completed the set up. Love the set up. Easy procedure once you do it a couple of times, and I don't even feel the Fiesta is back there.
