I am worried that valves and water lines will freeze without me draining the whole rv even though I will be putting in the RV anti-freeze throughout the whole system ?
If you can see where the pipes are coming up through the floor, that is where the valves should be, unless you have one of the fancy water command centres? These are not twist valves generally, they are pull up valves, generally white plastic tabs for handles. You do have other options though if you can't find them; you can use air (<50psi) to force the water out of all the lines first (pressurize then open each tap/flush toilet) before adding the Anti-Freeze, or you can just siphon in the antifreeze with the water in place. But doing the second one will probably dilute the AF somewhat, and you will want to run off more to get full strength in the lines. And assuming that is Mississauga Ontario, you will probably want your AF full strength.
Don't forget to pull the plug on the water heater as well and get as much water out of it as possible (98% empty). There will probably be a small amount left inside, but it has tons of expansion room so won't be a problem.
