What good are low point drains?
What good are low point drains on a trailer that is supposed to be good for 0 degrees? My drains are solid, slightly flexible, plastic pipe. It seems like they’re going to freeze and bust at anythin...

Low point drains (2) do not drain the tank. They only drain the piping system. The FW tank has it's own drain. Low point drains are not necessary if you use antifreeze, My 2011 32' Keystone sprinter has no low point drains.
My low point drains drain the entire system. Well, I guess that's not technically correct. My RV has 3 drains, and one valve just isolates the water tank.
Every time I'm done with the RV for a trip I pull all 4 valves and drain the entire system.
I don't even bother with compressed air as I tried it once and it blew nothing out - the low point drains are low so everything runs out the drains.
