Get a F350 dually.
Might as well tell him to go get a motorhome and tow the trailer with that.
The only difference with the GM 2500 and 3500 diesel trucks is the extra set of leaf packs on the 1-ton and I would expect the same to be true with your truck. The F-350 and F-450 pickups are little different than the F-250 pickup.
In the past the Ford trucks came with a rear axle and wheel bearings that were rated at 8900 lbs. and your truck is at least that good. Subtract the 3000 or so pound weight of the truck with nothing in the bed and that gives you a real load limit. Springs can be added as with Supersprings and tires can be changed out as well if more load capacity is needed.
With my GM 2500 there are two types of Supersprings sets that can be added to increase the payload to 4,000 or 5,000 lbs. and I opted for the 5,000 lb. capacity as with a top heavy load like a camper, in a tight turn more than 50% of the camper's weight is on one side of the truck.
Most E range tires are rated at 3200 lbs. at 80 PSI or 6400 lbs. for the rear drive axle. This is why the truck manufacturers take the easy way out and use an extra two tires to add 80% more load capacity. Easiest though not by any means the best approach which is why you will not see it done on military vehicles. There are Toyo and Nitto tires with a 3750@80 PSI load rating or even 19.5 rims and tires with a load capacity of 4,800 lbs. per wheel.
A dually or 19.5 wheels are needed with a dry camper load that is greater than 4,000 lbs. but the great majority of campers sold today are not that heavy. I would rather get a camper that can be used on a SRW truck than have all the problems of driving a dually (off the pavement or in snow or sand) with the camper on and the inconvenience of such a vehicle when the camper is not in use. There are good reasons why so very few people use a dually for private use with campers and even 5th wheel travel trailers.
With a trailer you have to add the tongue weight it generates to the overall load of the camper. Also a good idea to invest in a Superhitch and get compatible rear tie-downs from Torklift.
