De-winterizing is pretty much the same for most RV's. May be little differences in order from person to person, but it’s not that critical.
Drain FW tank.
If it had antifreeze in it, refill and drain until it all comes out. May take a few times...
Ensure HW tank has drain plug installed.
Connect Water hose to RV city inlet
Turn on each faucet "slowly" until it runs clear and turn off. (best to start at furthest end of RV) Do each one at a time... If you get a lot of pink from the hot water tap, that means your HW tank was not bypassed. Not an issue, you will just have a lot to drain.
Run shower and toilet until all clear. Run outside shower (if you have one).
Turn off water hose going to RV.
Fill FW tank while adding 1/4cup of bleach per 15G.
Un-bypass HW tank (assuming it was bypassed)
Using FW tank water supply, Run hot water faucet to fill up HW tank. When its full, air will stop coming out of faucet.
Run water from FW tank through system at each faucet (shower and toilet) until you smell bleach.
Turn off water pump.
Let it sit 24hrs
Turn on water hose going to RV (faster than using FW tank and pump)
Run freshwater through each faucet until you don't smell bleach. (you can manually drain and refill HW tank to make it faster)
Drain FW tank and refill with fresh water. 2 times to remove bleach.
Ensure your HW tank has water in it before turning it on.
