I would definitely consider replacing the frame which is probably your safest and more reliable way to fix the cancer. From what I can tell from the pics no matter what condition the rest of the truck is in that frame once you hit a trail with the load of it occupants, gear, fuel and the bounciness of the trail your bound to crack it and worst off even get stuck with a frame and cab bent like an A Frame. Removing the frame is definitely not the easiest job but that what will pretty much fix the problem. If the guy gets in there for fix that he's going to patch it really here and there and that's bad dude! I agree with the other members who said what about body bushing mounts those must be wickedly shot too! BONDO AND PATCH PANELS wont fix that even in the best conditions. You got to remember that is still growing inside the frame in parts you don't see so in my opinion patching that is just going to get ya to loose some coin on the deal only to be really disappointed months down the line when summer hits and the heat accelerates all that cancer like a California wild fire!Don't chance it either replace the frame or take some pics, post it on craigslist and let that be someone else's problem.
