In my article how to winterize an RV, I mention that you will need RV antifreeze to winterize your camper. Here I list my Top 4 Best RV Antifreeze.

RV antifreeze is very different than automotive antifreeze. Though they both perform similar functions, RV antifreeze is non-toxic, while automotive antifreeze can kill you.

RV antifreeze has to be non-toxic because you’ll be running it through the plumbing in your RV, which ultimately runs your hot and cold drinking water.

But remember, just because it’s non-toxic doesn’t mean it is safe to consume. It is not so keep away from children and animals.

Here are the Top 4 Best RV Antifreeze you should consider for winterizing your RV.

RecPro RV [My Top Pick]

The RecPro RV antifreeze is a non-toxic antifreeze that will give you burst protection to -50 degrees. This is a 4-pack of one-gallon containers. It will not harm steel, plastic, copper, or brass. You can safely used it to winterize your RV. It gets very good reviews online.

Splash RV/Marine

A runner up RV winterizing product.

The Splash Brand RV Antifreeze is another great product I recommend and a good runner-up to my best RV antifreeze list. It is highly rated on Amazon and is very affordable. This is a non-ethylene product made with a plant-derived additive. It offers burst protection down to -50 degrees. Also, it is biodegradable and non-toxic.

You can use it in your RV, boats, spas, hot tubs, etc. It comes in a one-gallon just that weighs about 8 pounds.

Camco RV Concentrate

Camco takes a slightly different approach to give you an RV antifreeze. This antifreeze comes as a concentrate (36 ounces) in a one-gallon plastic container. You then add water to make one gallon.

I imagine the reason they do this is to save on shipping costs. It’s cheaper to ship something that weighs 36 ounces rather than 8 lbs.

The Camco RV antifreeze gives you burst protection down to -50 degrees like all the others on this list. It is non-toxic and 100% biodegradable.

This package includes two bottles with 36 ounces of concentrate each. Though it is very well rated it is rather expensive compared to some other brands or what you might be able to purchase locally.

Peak RV

The Peak RV Antifreeze comes in a one-gallon container. It has burst protection down to -50 degrees. It is a non-toxic formula that is safe in your RV plumbing. Very similar to the other products reviewed on this page.

Camco RV Winterizing Kit

If you don’t have everything, you need to winterize your RV, consider buying a winterizing kit that includes just about everything you need.

That’s what you get with the Camco Winterizing Kit. It includes:

  • RV Antifreeze Concentrate
  • Had Pump
  • Blow Out Plug
  • Mini-Dehumidifier
  • 20-liter Bucket
  • Step-by-Step Guide

Overall this is a great winterizing kit that is highly rated on Amazon.

Best RV Antifreeze Final Thoughts

Any of the RV antifreeze noted above will do the job quite well. Where I have a problem with all of them is the price. They tend to be more expensive than what you can find locally, and due to the weight of the bottle (6-8 lbs), shipping is also going to be high.

I recommend you only order online if you are so far away from an RV dealer that it doesn’t make sense to make the trip.
