I am thinking of purchasing a new truck to pull my boat out of the water occasionally...mainly for maintenance reasons. I can't really see purchasing a 4X4 if I only pull the boat occasionally...once a year or so. In any event, I'm figuring the boat and trailor and contents probably run in the neighborhood of 3500-4000 lbs. The truck I'm looking at is the Nissan Frontier Crew Cab which is rated to pull up to 6300 lbs. Does anyone know if a 4X2 would be sufficient to pull this load?? The launch ramp is not real severe. Any thoughts would be helpful.
