I suspect if you are already worrying about mileage that you won't be comfortable towing the weight you're up against. Large TV's and large RV's don't come at a bargain price. A mile or two better per gallon rates way down on most owner's lists. And if it does work, why do you suppose the manufacturer didn't go with it? Like these aftermarket companies employ better engineers than the big three....I think not.
