Using RV when winterized?

Need to winterize my 2001 Jayco class C because is going to be 20degs. tonight. The RV has a clear hose coming from the water pump to suck the antifreeze out of the bottle to fill my water lines. Question is can I still keep water in the fresh water tank and use it? We are planning on using the RV this weekend and will need to have water for the toilet and shower.

Winterize the whole rv. Then set it up again for the weekend. That will be much less effort than replacing broken water lines.

I think a lot of people only use the toilet after it's winterized. Just keep a jug of the pink stuff and "flush" with it.
If it's in the 20's and you want to use the shower I guess you could just keep an eye on things. If the coach is kept in the 60's or higher that could be enough heat to keep things from freezing underneath. I'm sure some winter campers will be here to help out soon.

Good luck!

What are the day temps where you'll be? For just a weekend's use, with enough water in the fresh & both waste tanks, it will take days/nights of temps below zero to freeze anything in them as long as day temps are above freezing. You can put a trouble light in the bay with the water pump to keep it warm in there as well.

How is it one careless match can start a forest fire but it takes a whole box to start a campfire?

I use mine all of the time after it's winterized. I use a waterline plumbed to a 5 gallon plastic bottle filled with windshield washer fluid to flush the toilet. For washing and other hot water jobs I have a large old school aluminum coffee maker that holds a couple gallons of water and use that as a water heater. Works quite well. I will go camping several times in the winter when the temp is in the single digits.

The biggest problem you might have is at the dump station. I know of one or two heated water one's but they are 250 miles from here. The rest shut off the water to rinse with. You may be able to use the outside shower or want a friend with a 5 gal jerrycan of water to help with the after flush cleanup. Tank heaters also help. ;-)

Just out of curiosity, where do you dispose of that toxic brew? Windshield washer fluid is Methyl Alcohol (Methanol) and usually a little Ethylene Glycol. It's not legal, or even wise, to dispose of it in a septic system or municipal sewage system.

BTW, it's risky if you leave it in the black tank for very long. They use Methyl Alcohol because it evapourates VERY fast when exposed to air like the huge surface area of a black tank, add a roof vent and highway driving (lots of air movement and vacuum) and it won't be very long before you have a tank of nearly straight water.

Why not just use RV antifreeze? It's cheap enough.
