Water heater zinc rod

I was killing time in a camp store and noted that they had quite a few zinc anode rods for water heaters for sale. My travel trailer is 4 years old. The question is how long do these rods normally last and how can you tell if yours needs replaced?

Pull out the drain plug. If it has a long wire that looks like a badly decomposed corn cob, you need a new one. If it looks like the new ones, you are okay. If the plug doesn't have a thing that looks like a decomposed corn cob or a new one, your brand of water heater doesn't need one.

Atwood is the predominant water heater found in Jayco products and doesn't use a sacrificial anode. Suburban water heaters do, though.

My drain plug is plastic and I'm pretty sure it is an Atwood so I guess I quit thinking about anode rods.
