I should have known this was coming after rust took out my muffler, AC line, and gas tank over the last few years, but was always too busy to look into it. This summer for the first time in many years I had the time and ability to do some work in my LC, and here is what I found. While changing the oil, I noticed a small dimple on the front passenger side of the frame. It was soft to the touch, so I tapped it a bit and some rust fell off. I tapped it again and again some more rust fell. This is interesting I thought, let's see how far this goes. Well about 10 minutes later, this was the result:

Obviously this is not good - what would you do if this were your vehicle?

There's a lot of factors. How many miles, what condition is the rest of the truck in? If it has a lot of miles and is in average condition, I would say it is a parts car.

The rear is probably worse.

If it were mine I would not drive it with the frame like that.

It's like 10" of a 18 foot boxed frame, it's not dangerous.

If you intend to keep it for awhile I would treat as much as possible with a rust item like POR-15. For the section(s) of frame like that, that are eaten through I'd probably weld in some plates/sleeves to add structure and rigidity. Keep in mind, if you do weld over it, you're basically hiding the problem, like diamond plate corners on a 40, so I'd thoroughly treat the rust you're covering.

Here's some more pictures of the frame - other than the rusted out section, rust on rest of frame mainly on pinch joint in the middle. One section of the cross-section has some pretty bad rust where steel in coming apart in layers. Finally gas tank cover has surface rust, but tank itself rusted out a year ago and was replaced.
