I have read that it is a no-no to allow the RV antifreeze (pink stuff) in the water heater. I am not sure exactly why. Snip...
The reason is that you will get foam for a LONG time when you start drawing water from the heater in the spring. Even after flushing it out the foam will continue. It does not hurt the water heater but is just a pain in the neck. Same is true of the fresh water tank.
Best is to drain and bypass the water heater, and put a winterizing kit on the pump so you don't have to put any into the fresh water tank and draw from the gallon jug intead. Bonus is that you usually only need about one or two gallons to do the whole trailer or motorhome.
