Re: Water Heater (How Badly Have I Messed Up?)
When I had either of my trailers, I never bypassed the heater. If fact, I never used antifireeze because I used them more weekends than not in the winter. I simply opened all the low-point drains and left the water heater drain plug out. For extreme cold storage, I would blow the lines out with compressed air. I didn't want lose play time on the weekend having to flush out the antifreeze and then re-winterize it.
