Expert Reply:
Doug, typically about 2–3 gallons will do the job on a travel trailer, but on a class A you are better off with about 4-5 gallons. Since Prime Guard comes in a six-jug case, you’ll have plenty.
If you’re in an area that dips below zero, use the premium -100°F # PG96ZR otherwise, the –50°F # PG36ZR or # PG56ZR will do great.
How’s your rig stored - covered lot or open pad?
