Hey all, I have a 2011 ford edge with out the tow package, with out the package my limit is 2000. Pulling two skis on a double trailer plus passengers and cargo and I'm at about 2300 to 2700 depending who's comming with me. Trips are only about 30 min max one way. Is it possible for the tow package to be installed to get me up to the 3500? Engine is the 3.5 liter, FWD
