1) Coach was brand new when we picked it up in March - have never checked the anode. We have been on the road since July - 6 months into a planned 18 month adventure and also did a week plus shake down run prior to heading out for real.
I figure we camped about 3 weeks a year on average previously and think this would be a good estimate for most campers. Our 6 months non-stop would equate to about 8 years of use at the three weeks a year rate!
Our previous rig did not use an anode in the water heater.
And finally, my plan is to never have to winterize again!
2) It is a Suburban and here is a pic of the little guy to confirm it for you!
Appreciate you all and Merry Christmas to you and yours...
That is exactly what I have. While I will never come close to 6 months continuous, my hot water tank is filled with fresh water 95% of the time, today with 16 degree temperatures is exception. The suburban manual has a picture of when they should be replaced. For what they cost and maybe for you, if you pull it to check you might go ahead and replace? I don't. I put it back in unless less than 50% usage. Most people replace when they don't have to.
I guess you must be in areas where winterizing is never necessary, so yes you should pull just to eyeball it. When you do drain it, that valve on top is what you need to open to release all of the pressure.
FWIW, I have been using mine 3 years and replaced once and it still had usable life.
