My "Splash" brand gallon jugs of RV antifreeze that state its good to -75 were frozen solid on my shelf in the shop when it got to -22 last week..
What could have gone wrong?

I know that it gets slushy, but I don't think it freezes solid.

Urban folk tale. The truth is: diluted anti-freeze cools the engine better than undiluted anti-freeze.
But this isn't a discussion about engine anti-freeze.
The jug doesn't say it wont freeze. It says you pipes wont burst at -75.
Auto anti freeze can do the same thing. 50/50 mix will freeze around -40, but it can get quite a bit colder before the block splits. Just don't try to start an engine that has slush in it.

It will freeze but not expand much at all.

I put some in the toilet trap at our cabin, we don't heat the main floor in winter, it gets slushy, but nothing breaks.

Found this on the manufacturer's web site:
"Because the stored system is not in use, preventing ice crystals is not necessary, and to do so would require the use of a more expensive product with a higher PG content. As an example, the -50?F antifreeze has a freeze point of +20?F while the -100?F antifreeze has a freeze point of about-20?F."

And do NOT put engine antifreeze in your camper, that antifreeze has to be non poisonous.

I don't know if it is the same for RV antifreeze, but for regular ethylene glycol (the green stuff), it needs to be mixed with water to keep from freezing.
Put simply, the water is the antifreeze for the antifreeze. Somewhere around a 70% mixture of antifreeze to water is the lowest freezing point.
If RV antifreeze behaves the same way, it needs to be mixed with water. The reason I could see to use it straight is that it is assumed that there is already water in the pipes that you are trying to protect.
