Why the large discrepancy in rv antifreeze prices?

That add is full of bad information. In the context of this conversation, who cares what the code is? It's just part of the bad information.

By the way, you can find Peak RV antifreeze for much less on Amazon too.

Per Peak, the product code is for their fresh water antifreeze, not an engine coolant. How that individual vendor is hawking it is on them, but has nothing to do with what that specific product was designed to do.

THIS is the right answer!

Prices are all over the place. Just bought Camco at True Value for $2.99 a gallon. Best price I've seen in a long time. I bought several cases.

The stuff from Amazon costs a lot more because there's shipping, packaging & handling costs buried in the "free shipping" price. If anyone thinks there really is "free" shipping in this world, then pigs really can fly... :R

If you go to the right places, you can get the PG AF at a minimal cost above the retail store pricing on the cheapo ethanol-based version. Most people don't understand there's two types of AF and buy based on sticker price. I get the PG type at a nearby independent RV repair/parts shop at a cost slightly above retail stores or RV dealers that sell the ethanol-based version.

The propylene glycol antifreeze is the good stuff and a much better choice. Won't evaporate and dry out in toilet or p-traps, will help lubricate seals, won't taint plumbing lines, is non-toxic and is non-flammable.

If you look at a jug of it in a store, read the label for the contents. Sometimes it's hard to find or the print is small and hard to read.

FWIW, I always blow our lines out when winterizing. Easy to do and a lot less AF is needed.

Some RV antifreeze are ethanol (alcohol) based, some are propylene glycol based, some are a mix of the two. Ethanol is cheapest and propylene glycol is highest, normally.
And some stores just charge more.
Some people have concerns about alcohol and rubber seals.

Here is the correct answer. Now use the good stuff.

X2!

HELLO!!!!

If anyone bothers to read the manufactures description of the product, they are BOTH fresh waste winterizing antifreeze for RV's, Boats, etc.

Folks, I think there's some confusion here.

If this is for the Potable Water system in his RV, then the $2.58 should be used.

If it's for the engine in his RV (truck/car) then the 15.00 one should be used.

NEVER PUT THE $15.00 AntiFreeze in the RV Water System. It's poison and will make you very very ill if you drink the water after it's in the system!!!!

The "Pink" stuff is what's used in RV's to insure the pipes don't burst from freezing during the winter.
