I camped at a site in Oklahoma a few years ago, the rotten egg smell from the water the campsite provided had such a strong rotten egg smell, I would never have hooked up a water line to it. Even their restrooms smelled of it. I opted for no shower, had trouble just using their toilets.
Iím sure you can get bad water from some water sources, but if there isnít a bunch of dead people laying around it probably wonít hurt you. In that case I think a really good filter rated for sulfer will take that out. The sacrificial zinc anodes are if your hot water heater just all of a sudden starts smelling like rotten eggs and you know the water doesnít cause it. All the drain plugs I have run across are 1/2 inch npt (national pipe thread) and I guess the Atwood hot water tanks like Iíve got either didnít have the anodes or they just used them for drain plugs. Iím pretty sure the home hot water tank anodes have a 3/4 inch npt so some rv tanks might use that size??
Iím not an expert just saying what Iíve come across.

Forgot to mention, the anode rod is to keep the aluminum that the tank is made of from corroding away and eating itself. The same reason that boat motors, ships, barges, ship lock gates(Mike Rowe show Dirty Jobs) have sacrificial anodes because the electrolysis eats metal and the anode erodes easier than the thing it is protecting.

Forgot again, I read that aluminum which rv hot water tanks are made out of and magnesium which is alloyed with aluminum for some anodes, release hydrogen sulfide gas when they corrode which is where the smell is from

When flushing the water heater, be sure and shut off the electric element at the breaker and as a backup at the switch. Also shut off the gas switch as well.

NAILED IT. The Atwood water heater does not need an anode rod. Most Winnebago brand RV's came with Atwood water heaters. A water heater that smells like sulfur needs to be flushed and super chlorinated. In fact if the water heater smells like sulfur you would be smart to chlorinate the entire water system including the fresh water holding tank.

Chlorinating an RV's fresh water system and hot water heater is a simple process and will eliminate the sulfur smell immediately.
