Frozen hot water heater and covered storage

It came in early bout of bad weather this year and I got caught without draining the hot water heater. The water heater froze and was probably damaged. However, I think judging by the water stains on the insulation that it was damaged previously. After the thaw it appeared to be leaking.

I got the system drained except for the hot water heater and filled full of RV antifreeze again except for the hot water heater. I took the drain plug out of the hot water heater and it has been well above freezing for about a week now so the hot water heater is most likely completely drained. I expect to have to replace the hot water heater.  

The RV is now in the covered storage. The storage place does not have sufficient room between the fence and the garage to easily put the RV in it. Took me a long time to get the RV into the tight space.

This project is likely mothballed until spring.
