I pull my Cougar with a 2012 Tundra Crewmax. It doesnt know the boat is back there. I get about 10 MPG towing. Thats the only knock on Tundras, they have never been known for getting great gas mileage.The only problem with the camper shell is loading and unloading in the winter time by yourself. I launch at a few ramps that requires my back tires to be in the water and it since I have an ARE topper it gets a little tricky keeping your feet dry. I built a 4 2X6 that sits about 5″ tall and use it as a walkway if required. A man has to do what a man has to do.
