winterization question

[J&P RV]

Hello Everyone, I just winterized our new 322fks for the first time and have a quick question. There were 2 places marked as low point drains. 1 back by the bed slideout and 2 - together by the entry door. I had quite a bit of water from the one in the back, but nothing came out of the 2 by the entry door. The trailer was on a seasonal site and was pretty much level. Is this normal? I filled the system with anti-freeze working from front to back and hot to cold as they stated in the demo. Just wanted to make sure everything is done the way it should be.
Thanks in advance!

I have two other drains on mine and they are located under the sink in the bathroom. They are the pull up type (one cold & one hot). There are two plastic lines protruding from the bottom of the RV right below the inside valves.

The one in the back is likely the water heater low point drain. One of them up front is for the fresh water holding tank and the other is from the rest of your plumbing. This is the way it is on my trailer anyway.

Do you think it matters that nothing came out of the drains if the system now has antifreeze at every water point? I am thinking maybe there are valves like you have somewhere that we were not shown during the demo?

Thanks for the help! It is really confusing since the fresh water tank is marked low point just like the other 2. I would think they could just mark it as fresh water drain? I guess that would make it to easy!
