Where are low point drains?

I have a 2015 Thor Four Winds 31e bunkhouse and cannot find the low point drains. I did not winterize myself and user manual is not helpful.

two things you can do
crawl under the coach and look for tubing. The low point drains will have two tubes, a red for the hot line and blue for the cold..... well actually the colors may not be there for all coaches, i don't know.....
anyway, these will be open ended tubes sticking straight down.
Once you find that, you can chase down the valves just above inside.
In mine, I have a set under the bed and another set under the kitchen.
for the bed, I have to reach down through a wad of wiring to see two plastic valves.... pull the handles up/out not turn.
In the kitchen, I have to remove a drawer

The other thing you can do is to call Thor's customer service and request the plumbing drawings that will likely show them.

for the water heater, what I do is turn on the outside shower, which in my case is very near and just below the heater, then pop open the TPRV to vent the heater. I know the standard thing is to pull the plug, but the outlet pipe sits at the same level in the tank as this so i figure it's pretty close to the same thing.....
