RV antifreeze in MH hot water tank

I have a small trailer that I use for hunting and when I winterize I have to remove side panel and access is difficult. I have always avoided letting antifreeze enter hot water tank but I have never heard anyone state that having some enter the tank would permanently damage tank. I DO NOT have anode in tank. Question: Other than risking potentially foul smelling water, what is the danger of allowing RV antifreeze to enter hot water heater?

None. RV antifreeze is not harmful to your water heater. Depending on make the tank is either steel or lined with porceline. Other than a litttle extra time to flush it out in spring, no harmful effects.

And you'll need a lot of RV AF (6-gallons) if you are going to fill it. That's why the systems are set up so you can run it empty of water and just by-pass the tank.

That's 6 gallons MORE than what it would take to winterize it with water heater bypassed (at least). Even if you buy that 6 gallons of anti freeze on the cheap, it doesn't take long to justify doing whatever is required to bypass it.
