This evening was the first treatment of the sanitization. A cup of Bleach, 70 gallons of fresh water, pump to both sinks and let stand 2 hours.
The motorhome is leaning toward the drivers side. Must put down the jacks as the fresh water tank will not drain completly.
Man...dead battery!?!?!? Had to use the coach batteries to lower the jacks. Will check further on the condition of the engine battery tomorrow.
Drained and added a half cup of Baking Soda to another 70 gallons of fresh water. Hopefully this will get rid of the bleach smell. Letting it sit overnight. Will drain in the morning.
