I have a 2008 KZ COyote 16C and it only has one bypass valve shut off and it is the cold water one. Will this stop the antifreeze from going into the hot water heater? I'm also having trouble getting the plug out to drain the hot water heater. What size socket does it take? Is there an easier way to get it off?

I am not sure if you have a by pass on your hot water heater or not. There should be more than one shut off valve. They are usually mounted inside of your r.v. on the side of the hot water tank.
You could check with your dealer or manual to be sure. If you do not have a by pass I would be supprised but if not you can buy one at any r.v. supply store.
As far as the size of socket you need to get your hot water drain out. Measure across the flats of your drain plug and get a socket that will fit.

I think the socket is either a 1-1/16" or 1-1/8". You will need a 6" extension and a pull handle. They can be a bugger-bear to get loosened.

There are several different styles of bypasses, with one, two, or three valves.
The simplest has three control valves - one on the cold water to the tank, one on the hot water out of the tank, and one on a bypass pipe that crosses between the two other valves. To bypass, close the two valves to the tank, and open the bypass pipe valve. To use normally, open the two valves on the tank, and close the bypass pipe valve. While this has the most handles to turn, they are all simple on/off valves.
Another style has two control valves - the valve on the hot water outlet of the tank is replaced by a check valve -- lets water out, but not in. To bypass, just close the cold water inlet valve, and open the bypass pipe valve. To use normally, close the bypass pipe valve and open the cold inlet valve.
Another style (like mine) has only one control valve - the hot water outlet is a check valve, and the two other valves are replaced with a three-way valve. In one position, it closes off the cold inlet and opens the bypass pipe. In the other position it closes off the bypass pipe and opens the cold inlet. I assume this is the type of bypass the OP has.
There may also be another two control valve style that eliminates the check valve, and puts another three-way valve between the tank's hot water outlet and the bypass pipe. Both valves need to be flipped to go from normal to bypass mode. I would think this arrangement is uncommon because a check valve would normally be less expensive than a fancy three-way valve.
-----
Regardless of the valve arrangement, it should be pretty easy to confirm that you have the valves set properly to bypass the tank. If you flip the valves such that water flows to the hot side of the sink spigots, but no water flows out of the open tank drain, then you know you've got it set correctly for bypass.

What mfg. is your HW tank?
FWIW: If you don't have the exact size socket, you can put a small nail or brad in in the too-large socket to take up some slack....I do it every year when removing the anode rod for draining/cleaning----can't see throwing away $ for a socket I only use twice a year!
