Any thoughts on cause and solutions?

The smell is from dissolved sulfur in the water combining with dissolved oxygen to form sulfur dioxide (swamp gas). Hot water accelerates the chemical reaction. Well water is particularly susceptible; city water is treated to prevent/retard the reaction. Takes a few weeks of the water sitting in the tanks for the reaction to take place (in most cases).
When we were on well water, I found I had to drain the water after each camping trip to prevent the smell (usually camping once a month). Refill the tank and hot water heater when we were getting ready to leave. I started opening the tank drain (and cracked the hot water sink faucet) when we hooked up to leave the campsite.
One time, I forgot to turn off the water pump when I opened the drain as we departed. Burned up the pump.
Not an issue now that we are on city water - I never empty the tanks except for the winter.
hope this helps
