OK, so what happens when one tire on one side goes flat? The other tire has to take that one side's whole weight. Does not mean for sure that is one half, because the two on that side might not be the same. Usually they would be the same of course.

Not necessarily. The equalizer between the axles allows the wheel with the flat to drop to the ground, so it's still carrying weight, almost the full weight as if it was not flat, so it should =not= overload the same-side tire on the other axle. If this weren't so, then every time you went over a speed bump in a campground, you'd overload each tire as you went over the bump. If a tire company is telling you that you need to replace the other tire due to an "overload", that's just so they can sell you another tire, and laugh all the way to the bank, IMO.

I did note after getting parked off the road, that while the shredded tire was on the ground (rim almost was, but enough tire remained so the rim was not damaged), the other tire that side was "showing" it had more weight on it than usual by being bulged at the bottom somewhat.

I suppose that means it was holding up more weight than usual but not necessarily double the normal weight as indicated above with the equalizer.

So the situation could depend on how long you had to go at what speed on that one tire before you could get off the road as to how much damage was done to the other tire. Just more to toss into the total mix of circumstances while figuring what to do.
