Hi all,
I have been putting off winterizing the water system until now. Next week we will be much colder, high in the 30's so I need to get this done.
I plan to pump in the RV antifreeze but I know I need to bypass the water heater. I am looking for some ideas. As I see it I need to add a shut off valve in the line to the HW heater cold water inlet. The challenge I see is the short amount of line between cold water tee fitting and the HW tank inlet. My idea is to extend that line, using a reinforced flexible hose, so that I can add a shut off.
If anyone has some pictures of how they did there it would be appreciated.

Go get an RV how Water heater bypass kit for less than $20 at just about any RV store.
http://www.pplmotorhomes.com/parts/rv-pumps-water/rv-winterizing-bypass.htm

I would drain the tank and blow out the lines first before engaging the valves on the kit and installing the antifreeze.

Ken's suggestion for a bypass kit from an rv store is good. They are very convenient and fit in a small space.
That being said, I have had bad luck with the valves in those kits. They have leaked and just this fall while winterizing, one of the valves would not turn. After I removed it, I found that a rubber seal within the valve had torn and jammed the valve. So it was off to the hardware store. I bought three independant, 1/4 turn ball valves. They take up more room and it is tight under the bathroom sink but it works well.
You need to block the flow of water to both the inlet and outlet of the water heater and also provide the bypass.
The kits come with 2 three-way valves which accomplish the same thing as the 3 individual valves. Flex lines from the hardware store can be used.
