There was one guy on here a while ago (Mr. Jimi...?) that passed a while ago and was doing a pickup bed conversion on a Ford chassis-cab. As I recall, it was much more difficult than expected due to frame width and body height.
On a side note, that's a great looking work horse you got there. It makes my little RAM 1500 and 10k dump trailer jealous.
The cc bed length is 9 ft min, so you would have to cut the back of the frame or move the pick up bed back and have a space between the cab and bed. I'm sure it wouldn't be simple but definitely doable.
The only problem might be poor ride quality, before the service body was ready, I had the truck for a month and drove it around a little it was so stiff you needed a kidney belt if you wanted to go for more than a few miles.
It was really brutal and did actually hurt. With that heavy body it is not bad at all.
Thanks for the comment on the truck, I finally own it

made my last payment. I have been totally happy with my choice to stay with Dodge/Cummins. Made it easier that I had a 2500 for 12 years before this one. But this was all new for Dodge, first year of CC, new 6.7 Cummins and a Japanese tranny! so it was not a sure thing. But now I know I could not of done better with another brand.
My trailer is 10 K also. I got it when I still had the SRW 2500, I thought it was so huge when I first got it. But this truck is capable of pulling more, if I ever need another i would go to 12 or 14 k, only problem with 14k is that the truck is 12.5 so that would put it over the 26k CDL baloney. Maybe I could get a 14k and register it for 13,499.
For now the weight capacity is ok, I run out of volume with the brush at only 10 feet.
