Nissan may have a better answer. It does seem like the limit is the receiver, giving all the other specifications of that van.
First time I have ever seen a tongue weight spec in an owner's manual. What concerns me is that since the receiver itself isn't labeled with this spec, it's hard to say if the receiver itself is the limiting factor. It may be how the receiver attaches to the frame, or the strength of the frame where it attaches that is the limiting factor.
Could be they use one receiver that's rated at 1000 lbs across all models, then its capacity is limited by model based on how/where it's attached.
I don't have any specific knowledge on these vehicles, so just tossing this out for consideration.
