First of all, I just want to say that we have been towing our trailer for the past 15 years. But, when we purchased a lovely used 2011 Ford F-150 EcoBoost truck with built in tow package, we ran into a problem, our refrigerator was set for running on battery when we were traveling to and from the campground and the new TV did not charge the battery or provide power to the refrigerator to keep it cold . This is our first experience with having this happen. I've read that manufacturers will sometimes not fully wire the receiver. Is this true? When I take it in to the dealer what questions should I be asking them? I want to be prepared so that I make sure they rectify the problem. Experts what do you think?
