I have one for my Suburban WH, even though it drains slow I like it since I don't have to remove the rod to drain the WH which is not the easiest thing to do. Will remove and inspect the rod in two more years to see how much is left; the original rod (w/o drain) in the WH was well corroded after seven years.

LOL and while I won't recommend it my last trailer that I owned for over 25 years and was 26 years old when I traded it in had a Suburban WH in it. I never removed the plug/anode, but did finally replace the WH after almost 15 years for nothing more than it just seemed I should and for the next 10 years never a problem ... no leaks, etc. IMHO these things are built or at least were a lot studier than we are lead to believe.
