It's really just some pits in the top flange caused by an old homemade bed that the previous owner put on. The truck apparently sat outside and it would gradually get wet between the top flange and the 4x4 that laid on that flange. I could probably just leave it, but the metal gets a bit thin in a small area. This truck is just used to go to the store once in a while, and a short joy ride now and then. Not going to haul anything heavy on it, got a 2002 Silverado for those jobs.
But to respond to your comments regarding frame repair, I'm sure to properly repair a truck frame one should know what they are doing. The steel type, welding abilities, etc... are all things that should be addressed with importance. If I was using the truck for daily chores, consistently hauling things I would definitely have this looked at by a professional. I am confident I can repair this little area, but I also need to learn more about frame repair, you never know when you might need to do a more extensive repair. Sorry to keep babling on, thanks for your interest in this post. Have a good evening everyone.
