The anode rod uses a 1-1/16"socket. Suburban's specifications say that if the anode rod has lost 75% of its original weight, it should be replaced. Unless you have a brand new one to weigh for comparison, it will be hard to tell exactly. However, if most of the metal is anode is corroded down to the metal core wire, it is probably time to replace it.
Please ensure that the HW tank is COLD before you remove the plug. The last thing you need is to be hit with a gusher of scalding hot water.
As for antifreeze, I used the winterizing connection and the pump to pump RV antifreeze through my system. The tank, once drained through the plug should be fine. I did want the pump protected, something which air purging of the lines does not do.
