The Nissan Pathfinder V6 claims 6,000 lbs towing. I have heard that you should not tow more than 85% of the maximum capacity which would be 5,100 lbs. I want to tow a Malibu LSV 23 a few times a week which weighs 4,900 lbs with trailer add fuel, stereo, and gear and I am sure to be over the 5,100 lbs.
I like the pathfinder as a daily driver for its gas efficiency compared to other models. If I move up to the V8 I lose all the efficiency.
