Thanks for all the comments.
I lucked out and was only camping fr a few days. It only leaked when I had the pump on and I was able to keep a dry towel under it to keep the cabinet dry.
I will get one that I can control from inside.
I doubt the anode rode was ever replaced. That's how it was when I bought it.
Electric would just be an added expense and seldom ever used because I seldom stay in RV parks where i have access to power.
I thought bout taking the one out of my other camper but its 25 years old too so I doubt that it has much life left in it either.
I guess the search for a replacement begins.
