Draining water heater, put anode back in or not?

Got home last week after a 4 month trip in wives trailer. First time we've ever owned a Suburban water heater with the anode. We won't be using it again till mid June for a 2 month trip. How is...

Anode rod deteriorates vs steel tank. In doing so 'stuff' can accumulate...that is what flushing tank helps remove, so remove rod/drain tank/flush then reinstall anode rod to keep bugs/insects out and protect threads.

It is a 3/4" drain hole........for a reason. So that good draining/flushing can be done and so that a large anode rod can be inserted.

Suburban recommends anode rod replacement when 75% of material has deteriorated.
