Hi Kenny!

Yes! The Prime Guard RV & Marine Antifreeze # PG36ZR is both glycerin-free and alcohol-free. It uses a non-toxic, propylene glycol-based formula that's safe for RV and marine fresh-water plumbing systems.

It also provides burst protection down to -50°F and comes with six 1-gallon jugs.

What kind of RV are you winterizing?
