Agree again with Bob. In our case it is a 1997 Mercury Mountaineer (As a WVU grad, what else could I buy?) We tow double stacked Hobie 17's plus a 12ft Zodiac and 5hp(four cycle) outboard motor. Alternate tow is 21ft SeaRay Sundeck. With the Hobies and Zodiac, 15mpg, with the SeaRay, 11mpg at best. So mileage pulling the SeaRay is not good, it is still about three times better that it gets in the water. BTW, they both have the same 5 LT V8 engine.
