Sure it will, be sure to read the label if you intend to dilute it, most RV antifreeze is made to be used straight.
 
It's propylene glycol and water. Pretty harmless stuff, good compatibility with rubber.

Can't see any problems with it as ballast.

Since it is already mixed with water, don't see where a little more would hurt.

You could dilute some and put it in the freezer, see what happens.

Wonder what it weighs per gallon vs. a strong CaCl2 solution?

Maybe 60 to 70% as much?
 
Actually in terms of refrigeration that is not real cold. Liquified Natural Gas is chilled to -260F, see link. A facility I went to in Sabine Pass, LA on the gulf had 5 huge tanks ..200 plus ft dia.. they stored it in. There was another facility down there that had 3 tanks. They load it on ships for other countries.
Poke here
 
RV antifreeze is a mixture of water, propylene glycol and ethanol. The -100F claim is a bit of an exaggeration; note that it says waterlines won't burst, not that they won't freeze. It's non-toxic, which can't be said for ethylene glycol automotive antifreeze or methanol windshield washer fluid.
 
Try that a couple gallons stuff up north and your tires will be froze solid. Chloride is about 12 LBS to the gallon and Antifreeze like that is probably lighter than water with alcohol in it. Maybe 7-1/2 LBS to the gallon. Would have to weigh some to know for sure. Chloride will not hurt the wheels/rims if the leaks are fixed when it starts leaking it is the long time later that eats them up.

I could not see how it could freeze "solid' at anything less than -100 deg. F if, as they claim, it won't burst pipes at -100 deg. F.
A little research indicates that it will begin to "slush" up at -20 deg. F.

At anywhere between $7 and $10 per gallon, I would not call it "dirt cheap" however!

It wouldn't freeze solid, I have no idea why one would say that. It's entire purpose it to prevent waterlines and tanks from freezing and bursting.
However, it's also no where near $7-$10/gallon. It's about $2.50/gallon in the fall. He probably found it on clearance somewhere since it's off season.
 

Guess that begs the question, would old engine oil and hytran be good for tire ballast? It would be heavier than antifreeze.

I kinda doubt it would be heavier than anti-freeze.
