Winterizing 2008 Southwind

I am going to winterize myself for the first time. Here is a pic of the water heater bypass valve. I understand I need to bypass the water heater when I winterize. What do the other 2 hot and cold valves do? Do I leave them closed for the winter? Thanks.

Are they the hot and cold water drain valves for the system? Did you open them and see if water drains from under coach?

Hard to tell without being able to see where the various lines go. I'm not even sure that diverter valve is for the water heater. It could be for filling the fresh water tank from the city inlet. That appears to be the fresh tank on the left, and the two hoses to the right might be low point system drains.

Where is the water heater? In Fleetwood coaches, the winterizing valves are most often mounted right along side, where the tubing enters & leaves the heater tank.

These lines are right next to the compartment with the water heater so I'm pretty sure this is the water heater bypass. I have low point drains and fill/bypass for fresh water on the other side of the coach. I opened these valves and some water trickled out. When I turned the diverter valve to "bypass", the trickle stopped. So I assume these are to drain the water heater?

Also the blue and red lines go straight to the ground.

I am pretty sure to drain the hot water tank you should remove a plug near the base of the tank. These lines and valves in the picture will isolate it but not drain it.

Yes. I talked to local dealer and he showed me where the drain plug was. He said the other lines were just general system drains. Thanks!
