All rust is fixable just depends on how much time and money you got. That’s quite cancerous and with it also being on a body mount it is bound to break eventually. It looks like it’s at a spot where it makes a T in the frame. Your best bet is to pull the cab bolt cut out the rusted section and make a frame repair. Tons of videos on YT for frame repair work. Not an easy job considering you’ll have to make a new cab mount which is another job on top of the repair
So I just looked at the picture better and realized it’s not the car frame and is the body frame. Things get a little more tricky with body repair work and I don’t know anything about body repair. If you don’t wanna go through the head ache to try and fix the rust you can always put on a new cab
Zoom out a bit, post more pics of the entire underside. Differentiate between frame and body.
HJ81 5 speed, HDT truck?

yes truck is a 91’ HDJ81 with a factory 5 speed. Here are some more pics of the rusted area.
Yes, it's all fixable. Someone got heavy handed with some kind of coating spray. To really see where it is
I'd recommend going the long route. Remove the interior, and get down to the floor from inside so you
can see the areas of full penetration of rust. This isn't going to be easy. This is a case of until you really see
it all you won't know how to proceed.

i want to do this right so ill defenitelly be taking the carpet out and see from up top what im working with.
I would consider having a sandblaster guy remove that nasty 'spray tar' on there and get down to the metal (or rust) so you can see the extent of the damage. This is fixable, but it's not a 5 minute job. All that 'spray tar' should be removed, but you can start with the worst areas (in your pix) to minimize the distraction for now. Clearly this truck came from a wet/salty climate.
All this tar coating is doing right now is promoting rust, so get it off there (you can scrape by hand, where possible). Long term, you need to fix the rust and then coat with a non-drying rustproofing (not sound deadener) like Fluid Film or just plain old axle grease. You live in FL, so you will need some form of non-hardening anti-rust compound on there just due to your humidity and salt air.
Unless you have big frame issues not shown, I wouldn't be afraid to drive it.
