It can be done...but I wouldn't do it.
My buddy uses a Ford E350 2015 with the 5.4 liter motor. Pulls a Bullet Ultra Light (Don't know the exact model).
There are six of them.
He hated towing over the Rockies.
Another buddy has a 2015 F250 with the gas 6.0 pulling a Wolfpack (Don't know the exact model). There are five of them. He also hated pulling over the Rockies. He was doing 35MPH at 5500 RPMs in the truck lane. He told me this after they got back July 2019.
You could start out with what you have. Since you are going for a year, is it in your budget to upgrade if you don't like your setup?
Good luck.
