I purchased a 2011 Durango Citadel AWD. We are a large family looking to purchase a travel trailer. How do I figure out if I have the tow package or not? The dealer that I purchased it from was not very helpful and would only say "We're not sure, but probably not." The service after the sale was lacking, to say the least. They also told me that it did not have remote start, which it did. It has a 5.7 V8 Hemi and I see two plugs for a trailer on the hitch in the back, a 7 wire and a 4 wire plug. Any suggestions? Ideally, we would only tow it in about a 2 hour travel window. Nothing cross country. Just curious as to how much is too much or too long of a trailer to pull for our Durango.
