I have an 2011 F350 crew cab long bed dually. It has the Dana 60 in the rear. Is it possible to swap in a Dana s-110 into its place? Would I need to change the front axle too? What are the complications? I carry a 5000lb+ Truck camper in the bed and though I am about 1500 pounds under the Manufacturers weight I am over the trucks designated weight. I will be adding weight to the camper as I add insulation, different batteries and all in one converter/charger/transfer switch.

Anything's possible given enough time, money, etc.

But swapping the axle won't legally change the vehicle's capacity. I believe your original axle would be a Dana 80, but that's immaterial. The larger axle is probably set up for a narrow frame truck so spring mounts would be in a different place. If it's a 4x4, you need to be sure the gear ratios are the same, use an axle that has the same gear ratio as your front axle or change the ring and pinion on the front as well.
It might be easier and cheaper (better?) to trade for a larger truck.

The best I could do in this area is a 2017 crew cab dually which gives a payload of 6500 lbs. At a cost of $54,000. For a lot less then that I might be able to do the swap.

People don't realize how heavy slide in campers are. You are ok if you are 1500 under the trucks designed weight. insulation doesn't weight much. Batteries are about 60 each so you would have to add a lot more to the truck to be over. Just keep in mind axle and tire load capacity and you would be good to go.

Dana 80 weight limit is 11,000 lbs by its self. Its the spring package and other component's that de-rates the load capacity. I found myself in the same situation years ago with a 2002 F350 dually. I added an additional leaf spring to each spring pack. Then added a set of Timbren for the rear. The trick with the Timbren is make sure you load almost all the over load springs before the Timbrens touch the bump stop pads. You can cut the bottoms of the Timbrens off a little at a time to tune them in with a band saw. If the Timbrens are carrying to much load the ride will be harsh.
I recently bought a 2008 F450 pickup. It has the S110 rear. But in order to make the F450 ride better Ford put a soft spring package on the rear. I was most disappointed when I placed my service bed on it and saw the truck squat down. I the whole point of the F450 was to better carry the weight. I was able to find an extra leaf spring from a company in PA. the spring was almost as long as the main spring and did a perfect job. Needed longer spring mounting bolts as well.
