Are you sure that the treads are stripped?
Suburban tanks and anode rods have tapered threads...thus it might seem like it is failing and won't screw in all the way. That's the way they work..
Wrap a couple of turns of Teflon tape around it and if it doesn't leak you are good to go.

Nope....
Threads of drain hole and threads on anode rod cut thru the Teflon Tape and make metal to metal contact.
Teflon Tape just fills the voids between threads and that is how it provides sealing
