K20 Vs K30 frames

[66gmcguy]

Howdy all. I am looking for some opinions. I have a 1982 GMC K2500 camper special and the body on it is completely smoked. There isn't one decent body panel on it, so the plan is to slowly collect good body panels, paint them to match, then put together a nice clean truck. I recently picked up a K30 parts truck for the cab that's on it, and I was thinking about using the chassis too. But I just discovered that the section of frame between the front bumper and engine crossmember was cut off and replaced, and whoever replaced it did a piss-poor job aligning everything, so now I don't want to use this frame. I do have a clean C30 chassis that I could use and put all the 4wd stuff from the K30 on, but it seems like it's going to be a fair bit of work. My question is: is it worth it to go through all that trouble just to get a K30 chassis? My goals with the truck are to eventually put a duramax or cummins in it and use it to pull a 10k pound trailer. As far as I can tell, the only difference in the frames is that the K30 frame is taller underneath the cab. The steel is the same thickness between the K2500 and K30. So what do you guys think? Keep the K2500 chassis or do the work to make a K30 chassis?
