We're getting a Nissan NV 3500 passenger van to tow our trailer. My question -> I am trying to compare HP, Torque and axle ratio for the same sized engine in different years. When compared and shown by Nissan they do not use the same RPM for measuring the specs. In the real world pulling our camper is the difference in HP and Torque a big deal or not? Following is background information and factory spec comparisons with links to Nissan.
We just put our 2016 RAM 2500 Diesel up for commission sale at local dealer. Spent 2 yrs on the road with our 1974 Argosy 22. Trailer weight 5K. Wonderful first tow experience. But sometimes good times get molded into to new paths and we settled down in Oregon. Hard choice for us, getting rid of the RAM, but the RAM is just to much truck to keep paying for and mainly have it just sitting in the yard now. For the next 6 years we will be summer and vacation campers while daughter finishes school.
So.... needing a second daily driver vehicle capable of hauling our camper and kids, we're opting for a newer van. Most vans if configured properly can pull our 5K pound trailer. We also have two big dogs and need cargo space and room. But coming from the RAM it feels like a tow down grade. So I wanted a vehicle more than less capable. That pretty much set the bar for us looking at the GMC/Chevy 3500 and Nissan NV 3500. We're opting for the passenger vans due to the additional passenger safety airbags, installed seats for our daughter, creature comforts, and these passenger vans can be configured from the factory for towing (external transmission cooler, higher output alternators, wires, tow-haul mode, etc) as well.
We decided on the Nissan NV3500 passenger van. A 2016 and a 2018 are available right now. The only real difference is in 2017 Nissan upped the engine HP/Torque and added an available 5 to 7 speed transmission. Actually looking at the specs for the transmission the "5" has 5 forward and reverse. The "7" has 6 forward and reverse. One year they did not add reverse in counting the number of gears and then in later years they count reverse as a gear and called it a seven speed transmission. In actuality comparing apples to apples 2016 is 5 speed transmission and 2017 is a 6 speed. And there are different axel ratios.

In the real world pulling our 5K max weight camper is the difference in HP, Torque and axle ratio a big consideration or not? Will the 2016 tow just as well as the 2018? Its $20K cheaper! Thanks
