Oil. Very simply put. Even if a guy only has a pump oil can.. do what you can in the frame (when new or not rusted). It'll migrate around over time. Stop the rot. Every couple years a re-application.
If you have rot like the OP showed (back then), you might as well plan on cutting a good portion of the lower frame off and welding a new 'bottom' 1/3 to it. Most metal-shops have a big metal 'brake' which can custom bend a U-channel to your needs if you make a template and take it to them. The new metal will be standard mild steel but if your truck is a pavement-princess... If I was towing backhoe's on 5th wheel trailers, then a guy might run into frame-strength issues. Some states won't allow frame repair either.
But start with the oil if you're in the rust zone, esp if your frame appears good now. Or they make rust-proofing products. Problem with those is they generally require a bigger 'lift' to do and most guys never do them. Whereas an oil can you can grab off the shelf start squirting.
And while you're at it, shoot some in front of the box wheel openings (front meaning in front of the rear wheel into the gap of the wheel arch). Tailgate, doors, rockers, rear of box, and around the wheel lip.
Or, find a place that'll treat your truck and frame for a couple hundred bucks. If you are going to have a place rust-proof your tk and frame then hold off on the oil. Let them use their product. Main thing is to do something sooner than later (which usually means never ..for most tk owners).
