transmission cooler
our tv is an 05 GMC Envoy 8 cyl 7 passenger. comes equipped with hitch receiver and all needed wiring. we (wife and 2 kids) are towing a 2619 with air, awning, etc.There is no transmission cooler, do we need one? Tow capacity as is, is 6700 lbs. We will be travelling NY, PA, MA. Don't want any breakdowns nor do I want to void the warranty. Any feedback would be appreciated.
