There are 2 things you're looking at here.
First, your numbers in your original post are strictly dealing with the hitch receiver that came from the factory. As DDC noted, those numbers look fine. But that only means that your hitch receiver is rated to handle your trailer's tongue weight while using a weight distribution hitch (hopefully you've actually measured the tongue weight at a scale and aren't going by a brochure number).
What Flybob is talking about is the Gross Vehicle Weight Rating (or GVWR) which is your van's maximum allowable weight including all passengers and cargo. The vehicle itself weighs a certain amount and the difference between the GVWR and the vehicle weight is the Cargo Carrying Capacity (or CCC). The total weight of your van, fully loaded with all passengers on board and trailer hitched should not exceed the GVWR. That number should be on a sticker on your drivers door. It's not uncommon for people to exceed the GVWR and its true that manufacturers build in some safety factor in their ratings, but if, and by how much, you're willing to exceed the GVWR is up to you. Adding air bags, springs, etc. does not change the GVWR. That weight is established based on a number things like the rating of your axles, wheels, tires and frame. Obviously you're not going to change axles and the frame so your GVWR is what it is.
