I've used two pieces of angle, both have ends bent at an angle, for years. The angles have small drop pins (i.e. bolt) that corresponds with holes drilled in the bed. They just drop in. I move them depending on what I'm hauling. For the camper, they're set at 50" (camper is 49"). They're only about 5' long.
Love Flatbeds and owned and used them since the 60s. Reality Check has the best suggestion. Just treat your camper, like a motorcycle and put a track in like you would the tires of a motorcycle, just wider to fit the width and length of the camper. I would put more height on the rails, side and front, to spread the contact more. Many have taken their flatbeds further, by installing tool boxes along side, on top and below the flatbed, as well as installing things you would not normally find on a Pickup. You can install DOT Propane tanks, under the bed as well as additional Potable and Waste tanks below. These additions will aid in lowering your Center of Gravity the fact that a Flatbed places a TC higher, above the rear axle, than a conventional pickup bed affords.
Also, attach your camper to the bed and not below it to the frame. The flatbed will torsionally move differently than the frame does, by design. Attaching your TC to the Frame will result in your TC being crushed between the two. Most Flat Beds are installed with compression springs to allow movement to occur between the bed and the frame. Which is good.
There a number of people here that have flatbeds, TC Life and btggraphix, immediately to mind and they are excellent in sharing what they know.
Have fun.
