Well some good news...after 2nd time plus a new anode rod and water filter and leaving the HW heater on the rotten eggs seems to have disappeared.
Thanks for all you replies. Much appreciated.
Happy  Trails

I would be sure to drain it after every trip as somewhere you are getting some water that is causing it.

Folks, y'all seem to be overthinking, and overworking this thing! The problem was apparently the anode rod. Once replaced, there should be no need to flush anything.
Glad you finally replaced the anode rod.

Just curious - how old was the anode rod? How long since the last sanitizer cycle?
Might help others stay ahead of the same problem.

It could be sulfur in the water or coliform bacteria that thrive in warm water while the rig is not being used. You can get it in the water tank too. Bleach and drain everything and fill and drain and fill and etc. Then drink bottled spring water! Many years cruising on boats taught me that tank water was not for drinking. Some people use cheap vodka to winterize and sanitize. Tastes better than bleach and makes lots of problems go away.

Replaced anode rod and sanitized system Nov. 4 have been on the road ever since. We do not use the fresh water tank always on city water. Interesting that the anode rod I just replaced had very little pitting on it normally I would have reused it...lesson learned.

Sorry for one more question.
What kind of filter are you using for city water?
And thank you for helping myself and others to be aware.

One more question....Did you re-install a magneseum anode rod or did you switch to the aluminum?

The Columbus has a WaterPur water treatment system with a Kw1 filter.

I installed a new magnesium anode rod.

I have seen the smell if the thermostat is set too low too. Not sure how / if this might apply but it happened to me.

I've own a number of apartments with tenant's complaint about sulfur smell it's always a by-product of the anode rod. It's not the anode rod's fault but that's where you have to fix it.
Hydrogen sulfide is what you're smelling. Either switch anodes to a new one, one of different composition or just remove it and replace your water heater earlier (maybe)......

This has been a great Thread. After reading all the responses I discovered an important fact (at least it was my observation)...not mentioned in FR or Manufacture's manuals. When sanitizing the water system you run a bleach solution throw the entire system including the hot water heater (understood) BUT when sanitizing due to "the rotten egg" smell the water heater must be on...I know this is old hat to you seasoned RVers but a lesson learned for this Winter Texan.
Thanks for your inputs.
Happy Trails

The root cause of the odor is bacteria and or sulfur in the water. Changing the anode rod will help, but if you use the suspect water source and do not drain WH after use odor can return.

Y'all pay attention here!
The cause was the anode rod!

I'm curious. What causes the anode rod to generate the sulfur odor when it's only a few months old?
What are the options for manufacturers types/quality?

X2.
Doesn't matter which anode rod you use or how often you replace it. If there's sulfur in the water, the smell will return.

Correct.
The ONLY way to eliminate the smell is to remove the anode rod completely and put a plug in its place.
Of course you lose the protection of the anode rod to the tank but only YOU will need to decide which is worse... the stink... or the protection.
Even without protection I had a tank last over 7 years and still going strong when traded... BUT... no smell!

I had the same problem. Rotten egg smell. It turned out to be the built-in water filter system in my Rockwood camper. I removed the canister under the filter connections and threw away the filter. Cleaned up put a new filter in and the smell never came back.
