Suburban uses an anode rod because tank is a 'glass-lined steel' tank.
Sometimes it helps trying to 'tighten' a stuck bolt FIRST before trying to unscrew it.
Anode rod is necessary to protect that steel tank from rusting out.
Suburban tanks are not available for replacement....have to replace WHOLE water heater
Drill it then E-Z out it
After removal.....use a 3/4" NPT pipe nipple to chase drain hole threads (clean up/straighten them)
I responded before seeing your whole post... Hmmm... Now I'm thinking of tackling it again.
If I "blow it" and end up needing a new tank, any advice on that? Recommend going back with the Suburban?
