I have a 2002 Ford Excursion with the V10, that I pull my fully loaded 9800 lb SeaRay 268 Sundancer with. Nice tow vehicle. Very comfortable and a lot of room. But it is a gas hog. If I keep my foot out of it with the boat in tow, (ie, speed limits), I can get about 10 mpg. Maybe a tad better. Without the boat in tow, I can get anywhere between 13-15.5 mpg, depending on my speed and the wind. Diesel is probably better, but with the cost of deisel, I'm thinking it's probably an even trade off. The only complaint I have about my Excursion is the brakes are not great. And it's not the easiest thing to park in a small parking lot. But it does tow! Colby
