So I have a 2007 Edge that did not come with the towing package and I had the dealer install a class 2 hitch at purchase. From what I have read the package upgrades includes a oil cooler upgrade, transmission cooler upgrade, battery upgrade, anything else? Now my new boat and trailer (no brakes) are 2800lbs, so I know some upgrades are in order. Are there aftermarket upgrades that may be better than stock towing package, can I even buy the towing package components to upgrade? Anyone care to estimate pricing? Should I even upgrade or consider trading up to say an explorer, hate to drop the mpg when not towing though.
