Make sure you run a charge line for the battery. We towed an 08 for years no problem. Bought our 14 and immediately started having dead battery problems. The new ones have so much computerized stuff running with the key in #1 position that even following the directions to start the car every six hours is not enough to keep you from a dead battery.
