We are going to buy a new truck as our little 95' V-6 nissan struggles to tow our 2,500lb. fourwinns boat as it is and we may buy a bigger boat next spring.... We test drove a Nissan Titan and neither the wife or I cared for it very much.. The toyota Tundra looks great on paper, better towing capacity, more power, quicker and faster than the titan and better mileage.. I was suprised to see the (relatively) low towing capacity of the Ford F-150 but would consider one as well as an F-250 (possibly with diesel engine)... Out of the above mentioned trucks, would anyone care to comment on durability, performance and mileage?.. I'm trying to educate myself on new trucks but there sure is a lot to digest. We will be looking at boats in the 5000-7000 lb. range.. thanks
