Hi AKthom, & Welcome To The Forum,
That would make a nice set-up,The Pros & Cons???? A Lot Of Work With The Truck Body Still Attached.But there are a few tricks to it,Unbolt the body jack it up off the frame and roll it back on a couple three steel pipes that are wider then the frame rails.Take the seat and glass out and cut the cab from the outside in.Do what ever reinforcing and filling to the cut cab section.Then transpose the pattern to the body and do the same thing,You will have to put a Sleeper Boot or
Seal between the Cab & Body.Roll the body back up adainest the cab & nail it down.If thats to much work,get in the cab
and smash the back window out then cut a hole in the body go buy a couple bicycle tire tubes put them between the cab and body and fill em with air. That way you can crawl through the hole,It's quicker & cheaper but looks like crap.Good Luck,
with the project and send some photos in of no matter how you did it.That way it can be admired or laughed at.I'm sure
there are plenty off ways to do it,Thats just my opinon and we all know about them.
