The 16BHS trailer will put you close to or just over limits specified for your Pacifica. You will need to be very careful how you load the van and what you take with you on the trip. Some numbers:
Gross Combined Weight Rating is 8600. Subtract the curb weight of the Pacifica (4330) and the dry weight of the trailer (3097) leaves 1173 for cargo. This doesn't look too bad until you look a little deeper. My Pacifica Limited is limited to 1150 for cargo in the van. I expect your L is the same (find the limit on tire pressure placard on drivers door jamb).
From the 1150, subtract 377 for the trailer specified tongue weight leaving 773 pounds for people and all the things you want to take with you. As mentioned earlier, you will need to be careful how you load the van and may be limited on how much stuff, by weight, that you bring on your trip. Leave the fresh, gray and black water tanks on the trailer empty when towing. You can't afford the extra weight.
Note the published tongue weight for the trailer, 377, exceeds the Pacifica's published limit of 360. Also the trailer frontal area, although not specified, likely exceeds the Pacifica's published limit of 40 square feet. Air resistance at highway speeds will put a load on the engine/transmission. You may need to limit your speed to 55 or 60 mph. Plan for longer travel time.
If you want to pursue this trailer, I suggest you gather up the things you plan on taking, including clothes, and weigh everything so you have a clear understanding of the total weight. I would also suggest you see if the dealer will let you take the trailer out for a short test run. And make sure you get mirror extenders so you can see around the trailer behind you.
