2005 23' Flagstaff

Just bought my first TT, a 2005 Flagstaff 23.
Didn't expect to have to winterize it here in St. Augustine, FL but it is 22 degrees tonight.
The mechanic and I spent an hour removing access plates and stuff trying to find the low water poits where the water drains are supposed to be.
No luck - ran the water pump to empty the tank and pulled the loug out of the hater heater to drain everything, but aren;t there supposed to be drain valves on this thing?
Appreciate any help. Thanks

I know RV dealerships and walmart have this plug to blow out your lines. Being your in Florida I don't see it freeze for hours. You could also dump RV antifreeze in fresh water and run pump to pump through out RV.

The air blow out plug is all my dealership uses and I live in South Dakota. It was -15 last night.

EDIT: make sure to use a pressure reducer down to about 35-45 PSI anything above that you may blow up things. I just use the water pressure regulator then hook this to that.

Our rig is sitting outside with RV antifreeze in it, but this is the last year.

I have a blow out plug and will be using that. RV antifreeze still goes in the drains though and a bit into the gray and black tanks to keep the dump valves from freezing shut.

Don't forget to drain the fresh water tank with the spigot and then run the water pump dry before you blow out the lines. There is a check valve in there that will keep water in the pump if you don't) the pump could be damaged if it hard freezes.
