Smile IMO!

I use about 4 to 5 gallons. I believe better more than less and better safe than sorry so when I winterize I make sure I use lots.

Remember to do the outside shower and put enough down in the traps of the sinks.

I do ours with 2 gallons. Drain and bypass the water heater, blow out the water lines, pump antifreeze in until colored water comes out all the faucets including outside shower, inside shower, toilet, and ice maker if you have that. Pour whats left into all your drains and leave some in your toilet bowl to prevent the seal from drying out and you're good for the winter.

I use 1/2 gallon for the p-traps and the Splendide washer.
I gravity drain the wwter heater, and fresh water tank and system.
I do not pump any anti-freeze into the water system, (nor do I blow the system with compressed air)!
I have had NO freeze related problems, (11 Wisconsin winters).

I just did mine today. I used one gallon which was pumped through all the lines and the rest was poured into the drains.
I had pink coming out of all faucets which makes me feel much better after last nights low of 18 degrees.

I found out this year that I got deeper colored pink faster when I ran the water pump on the RV until the water quit flowing in the sink and than switched over to sucking up the pink stuff. I only used 1 gallon versus 1.5 gallons the last 3 times.

I did our 2007 Sightseer last week. Three gallons was more than enough. Pink stuff coming out all faucets, spray head and toilet. About 1/2 gallon in the drains for the shower, sinks and toilet. bypassed and drained the water heater, flushed the holding tanks and drained and drained the fresh water.

Zero.. Air is a much better antifreeze, Good to well over -100 degrrees.

Just remember to blow the lines out several times, NOT just once, pausing between blows.

You will still need 1-2 gallons for drains, traps and toilets.
