For those of you out there with low point drains here is a nifty modification I did for convenience. I cut the existing fitting off the pipe and slid on a full port 1/2" Sharkbite ball valve. Gives you positive closure on the system and you can open it slowly without the water running down your arm. The other end (1/2" FPT) allows the plastic plug to be threaded back in hand tight if you desire. Would allow you to quickly drain the system on the road for quick winterizing/repairs without tools.
Thank you Glenn and Myron. The 21is different, from my understanding there are drain valves under the entrance steps. My trailer has water lines (6/7') that are unsecured under the trailer, they just lay across the bath grey water drain line. I thought installing a low point drain valves and supports would help to secure the lines. I found this thread and wanted to see ETI's low point drain set up for the earlier E-21's.

It's my understanding ETI stopped installing low point drains shortly after Jan 1, 2014. While it drains the water system, it didn't drain the water out of the toilet valve and because folks weren't doing a proper winterizing, valves cracked. Replacing that toilet valve can be a PITA.

And I can confirm that ETI will NOT install them as an option either.
