Do you need a truck? If not it seems like fixing the oil pan slinging some spray foam and bondo at it and then throw on whatever type of bed/body you can get cheap (flatbed, utility body, doesn't really matter what you choose, the goal is to just make a complete truck) and list it for sale.
And you morons let running trucks sink into fields and then cut them in half to make trailers rather than making them run again. It's not like southerners are known for their economic efficiency, kind of the opposite really.
If you really want to do a body swap the 80-96 bodies basically drop onto the 99-04 frame. If you have an F150 you can drop on that's a pretty good upgrade for an old truck IMO. You can likely find an 80s F-series (or bronco, but you'll need to shorten frame and drive shaft to make that work) that needs a frame for cheap but it'll probably have a body in the same condition as what you got and that's more work that fixing what you got.
I always thought a bronco on a 250/350 7.3 frame would be a fun rig.
