Towing with NV 2500 van

Just went to the Nissan website. Looks like you have about 260 hp and 280 torque. Max towing is 6,200 lbs. I would assume that max towing of 6,200 lbs is lightly loaded (usually is). I assume if you need this van you probably either have a lot of people or cargo that would take up some of the 6,200 lb max tow rating. Add 1,000 lbs people or cargo in addition to driver and you are probably at 5,200 left on tow rating (which is probably GCWR based but I don't see the actual GCWR). You will probably be disappointed in performance since you would be towing more than recommended and it might take a toll on the vehicle over time.. The V8 has a tow capacity of about 8,700 lbs. That's really what you need to pull the 6,000 lb new one unless you have nothing heavy in the van. Good luck.

Gas engines need to rev, that's where they make there power. find out where it peak HP/TQ is and when its required to wind it up that will be the best rpm to run.

However, there is only so much a naturally aspirated V-6 can do. and with a 6k lb GVWR TT you are going to be in V-8 territory. better performance and mileage when towing!

You could always do like they did on Spike TV Xtreme Off Road, they took an NV 2500 and put in a Cummins engine and made it 4 wheel drive.

what HP is the motor producing at these revs? Probably what the motor needs to turn to produce the HP the motor has. Even if you had a diesel with similar HP specs, while not turning as fast per say, it would still be at whatever % you max hp is need vs redline. The motor is fine, as long as you are not having overheat issues.
