Mine was roughly the same and I changed it last fall at winterization time on our 11. 
Mostly because the previous owner had left me one so I used it.  If I would have had to go buy it I probably would have gone another year or two.

That rod is fine and should last a year or three.  I finally replaced mine after 4 years and didn't really need to, it looked about like yours.

All,

As per prior post, on my 2015 RP-179, I drained both sets of low point drains with faucets open.  After waiting till emtpy, I then unscrewed the anode to see if any water came out.  Result?  Only a few drips came out.  See dry horizontal surface of water heater compartment below; no water.  So, the low drain point caps does drain the hot water tank.  Thanks all for your input; glad this one is solved.

Also, check out my anode.  Should I replace it?  This is after 3 uses....

Fantastic advice from everyone; thanks!  After my next trip next weekend, I'll plan a test... 
1. Open all low point drains and faucets in trailer
2. Allow to drain completely
3. Then, unscrew anode noting how much, if any, water drains out.  I'll try to note amount of water.
I'll report results herein...
Thanks everyone for the advice.  :-)
Doug, thanks for the mpg info... I found when driving across country with my 179 w/o water using a 2007 Ford F-150, I was getting ~10mpg.

Interesting. That's good to know. I've opened up low point drains and let them completely drain but water still came out after removing anode. Not sure if I opened faucets after opening low point drains though.

 Another question on that, should we use that white thread tape whenever pulling the anode rod out? 


Yes you should use teflon tape on the threads.

Only about 50 pounds of weight, which will not affect your mpg if you are trying to improve it that way.  The wind resistance is most of the problem at highway speeds.  The mpg difference between my 3000 pound pod and 7000 pound Salem (both fully loaded):  17.5 not towing, 9.5 with the pod, 7.5 with the Salem.
