The way tow ratings work is this:
Your vehicle has a max GVWR (vehicle plus payload inside vehicle), and GCVWR (vehicle plus payload plus towed load).
That is Gross Vehicle Weight Rating, and Gross COMBINED Vehicle Weight Rating.
The 5k Max tow rating is dependent upon your GCVWR and GVWR. That is, your max towing weight is directly influenced by the weight of the vehicle, the passengers, fuel, everything.
Tow rating is GCVWR - ACTUAL VEHICLE WEIGHT = amount left over to tow. If you want to do it correctly, you'd weigh your vehicle ready to go before hooking up a trailer and see what weight you legally have left to tow with. Vehicle options, passengers, cargo.. all effect your vehicle weight. A loaded Platinum will have less capacity left to hit that maximum tow rating, because the vehicle itself weighs more and uses up more of the GCVWR. It may not even have enough capactiy left to even tow 5k. You have to weigh your specific vehicle to find out your specific weight capabilities, as every vehicle is differently optioned.
Don't forget that 10%ish of the trailer weight is tongue weight, and that comes off the vehicle's payload capacity. 15-20% if using weight distribution.
So, if you have 7 people @ 170lbs each, you're already at 1,190 lbs payload. 5k trailer would add another 500 lbs minimum to the payload. I'm willing to bet that would be over the max payload of the pathfinder before anything else.
edit: my 2017 has a payload capacity of 1149lbs.. So passengers alone is over capacity, not including anything else..And I believe 2016 and down is lower than the 17's.
