What size wheels and tires? Ford doesn’t offer the camper package on the 250/350 with 20” wheels.

For an F350 with 18” wheels, the truck is already fitted with five-leaf rear spring packs, so there's no rear spring upgrade like on the 250. The optional camper package just adds a rear sway bar, a camper certification, and (maybe) a slight front spring upgrade.

You can add the factory rear sway bar, or you Can install a third-party product (I.e., Hellwig). For a light camper, I suspect the front spring difference may not be a major concern, especially if Ford already upgraded your truck’s front springs to accommodate other options.

The camper certification identifies maximum camper weights with respect to center-of-gravity location ranges in the bed. As long as your camper’s fore-and-aft CoG is in a zone between 0” and ~18” ahead of the rear axle center line, then you're probably OK. You definitely don’t want the camper’s CoG located behind the rear axle.

The truck will have no problem with a camper of that weight, but try to keep heavy loads as low as possible. The camper’s wet / loaded weight may well be an additional 500-800 pounds more.

You’ll need to set up your camper as a trailer in the truck’s towing menu in order to activate the battery charging circuit. If your camper doesn't have tail lights, you may need an adapter.

Check the rear spring packs...They may be four-leaf packs.

Sounds correct. The four-leaf rear spring packs used on the F250 with the camper package and on the F350 with 17” wheels are a bit softer than the five-leaf packs on the F350 with 18” or 20” wheels.

Adding the rear sway bar, keeping an eye on the CoG location, and keeping the camper’s loaded / wet weight below 2500 lbs. should work for you. A trip to the CAT scales after you’re all loaded up might be a good idea.

What are your plans for tie-downs and turnbuckles?

Allow me suggest that you take a look at products from Torklift.. They have front tie-down arms that bolt to the sides of the frame (not belly bars), and the rear tie-downs attach to the sides of the hitch receiver. Not inexpensive, but an elegant solution.
