Assuming the high roof model and SV trim:

Payload = 3744
Tow rating = 9,500
The tow rating is overstated because it assumes nothing in the van except a skinny driver. So back that off to about 7,000 pounds gross trailer weight when the van is loaded with the normal stuff.
The payload is overstated for the same reason, but unlike most vans it probably will not be the limiter for the hitch weight of trailer you can tow without being overloaded.
So if the GVWR of your trailer is about 7,000 pounds - and not more than 8,000 pounds (and you don't haul a bunch of heavy stuff in the van), then that van should have plenty of power and torque and suspension and brakes to tow the trailer over the hills and interstate mountain passes with no problem.
Thinking about buying a Van instead of a pick-up because I have home stuff like a bed and 12 plastic boxes to haul.
I did something similar way back in 1977. I ordered a new Ford cargo van with the V-8 Windsor engine, windows with privacy glass all around, the fanciest trim available (Chateau) along with optional Flexsteel Captain's Chairs. Because of the Chateau trim and rear AC, it came with fully insulated walls and ceiling, but bare metal floor behind the front seats. I found two more matching Flexsteel Captain's Chairs in the bone yard. I installed plywood on the floor, covered with 2" of high-density foam rubber and thick plush carpeting. I also installed a second AM/FM radio with earphones for use in the back of the van so the 11 and 13-year-old kids could play their obnoxious loud music without disturbing the adults in the front seats. We towed a camping trailer and put over 100,000 miles on that van - coast to coast and border to border, in a little over three years. The padded floor made a good place for the kids to play or sleep while we were traveling. The self-customized van made an excellent touring vehicle for our family. Fond memories.
