You may have the wrong type of anode in your heater - verify the type (think it's magnesium not aluminum) because I had the same problem because I used the wrong anode. As soon as I went to the approved metal the issue went away. I am pretty sure it's magnesium you want, but verify with the manufacturer.

The smell of rotten eggs is hydrogen sulfide given off by dying iron or sulphur bacteria. It would have come in with well water from a campground, or a source of water with the bacteria growing in it. A good example is old cast iron city water piping at the end of the pipeline where flow is minimal and chlorination becomes almost non existent. Once in your plumbing, it can only be removed by superchlorinating everything, and or flushing with a surfactant. If you have a 100 gallon water tank, run it all out. fill a small amount in. 10 to 15 gallons with 2 to 3 gallons of bleach and a few cups of simple green. drive around a bit to mix it all up, then run each faucet, toilet, shower, hot and cold till you smell the bleach. Don't forget your icemaker. Let sit for 8 hours then flush it all out and rinse with clean chlorinated city water. If any is left in the system, it will eventually come back. When you flush, remove the aerators as they may clog with dead iron/sulphur bacteria sloughing off the pipes. Changing the anode as suggested may reduce the smell, but will not eliminate the problem. Aluminum and Magnesium anodes react with the bacteria differently, sometimes accentuating the smell.

If you get it you will remember it!!
Ugg!! I have always used chlorine through my system when it does occur. In my Coach it requires connecting a fill hose, then pouring it full with chlorine, then adding a water source to push the chlorine into the tank. A messy way to do it for sure, but very effective. Circulate water through entire system in clouding Hot Water heater, let sit over night. Drain system flush all lines clear of chlorine and refill. This has always worked for me!! It has only been necessary about 4-5 times in about 50 years of Rving. They make a tool for just that purpose! I saw one on line.
My plan is to make one the next time I encounter Rotten Eggs. 🤓🤓

I think you are on the wrong track. Check your batteries. Failing batteries will produce serious H2SO4 odor. I’ve had the problem twice with failing batteries- once with house bank, once with chassis bank.

It is iron bacteria which is generally harmless. We have it at our house when we are away for a while. We just flush the hot water heater and lines when we first get home and that gets rid of it. Just run the hot water at each faucet until you no longer get the smell and you should be good to go!

It's a bacteria odor, hydrogen peroxide kills it.
Rinse once and you should be ok.

2x that had that happen to me and that was the fix

Try replacing or delete the anode rod in the water heater, they attack those annoying chemical's

BEST PRACTICE is to ALWAYS DRAIN YOUR WATER HEATER BETWEEN USES.
Doing that will go a long way to eliminating bad odors and prolong the life of your water heater.
Here's link to the Installation, Operation and Maintenance Manual for Suburban water heaters.
https://www.rvupgradestore.com/v/vsp...tionManual.pdf
ANODE PROTECTION
The tank in this water heater is protected by a magnesium or aluminum anode to prolong the life of the tank by absorbing the corrosive action of hot water. Under normal use, the anode rod will deteriorate and because of this, we recommend it be replaced yearly.
NOTE: Water with high levels of iron and/or sulfate will increase the rate of deterioration; therefore, more frequent replacement may be required. If anode rod is mostly eaten away, replace it with a new one. (See Figure 12).
To prevent a water leak when replacing the anode rod, a pipe thread sealant approved for potable water (such as Teflon Tape) must be applied to the threads of the anode rod. Proper application of a thread sealant will not interfere with the anode’s tank protection.
Operating the water heater without proper anode protection will decrease tank life and will void your warranty on the tank.
NOTE: Tank is drained by removing anode rod, see the “Draining and Storage Instructions” section of this manual.
To extend anode life, drain water from tank whenever RV is not being used. Avoid any extended time of non-use with water in tank. Also, refer to section on Winterizing

So I have sanitized my and many other HW tanks over the years. It sounds like you have a filter which makes it an easy process. First drain the hot water tank. Remove the filter and add one cup of bleach to the filter canister and screw that back on. Open a hot water faucet inside somewhere hook up to water source and turn on water let it fill the hot water tank with the bleach water mixture. Let the bleach water sit in the hot water tank for about 15 minutes. After about 15 minutes open all the faucets let that bleach water run through the lines. A few minutes of letting the bleach water run turn everything off during the hot water tank put your filter back in. Turn water source back on let the water run so you don't smell bleach anymore in the lines all set.

When I added peroxide I unrolled my hose to empty and then filled the hose with peroxide. Hook back up, turn the water back on and open the hot water faucet in the bathroom. This should run the peroxide into the water heater. Let set a day and then drain water heater. Refill and check for smell. You also have on your heater anode rod which is to collect water problems. Either replace, it is a part of your drain plug, or remove completely, as on home water heaters, by just cutting it off completely

Rotten egg smell in water
I had this problem with hot water going bad in the tank. Suggest you drain the hot water tank and in future run the hot water out when your trip is over. That solved the problem for me

Holy rotten eggs
Does your hot water heater have an anode. That happened at my water heater at home. Changed out the anode and everything was fine.

Silly question but has anyone considered the possibility of anti-freeze leaking or being left in the HWH. Any amount, once heated, will produce a very nasty rotten egg smell.

Drain your hot water tank after every trip. And the next time that you take a trip run the water for a long time. I usually fill the incoming hose with bleach the first time that I go camping in a given year or after I accidently forget to drain the hot water heater and get the rotten egg smell. It gets flushed through your system and will not harm you since it is a small amount. All is usually better afterwards
