I know that I only have one switch inside the coach to start the heater. That seems to send a signal to an igniter to ignite the LP to start the heating process. The ignitor isn’t arching when the switch is flipped and the light that comes on during the “timed out” period doesn’t come one either, almost like leading me to believe it’s on and working. I’ll try to check what I can electrically then blow out the line and see where that gets me. I’ll check the model number however and get back to you, thank you.
So to recap:

You have a gas only water heater.
You turn it ON at the panel and nothing happens - no spark, no error light, no hot water.
Either the fuse that supplies the water heater is blown or another problem is preventing 12 VDC from getting to the water heater control board, or
Your control board is bad.

If you got the "Pilot Out" light (Atwood refers to it as the "lockout light") there would be a host of other possible trouble sources.

Here's a troubleshooting guide and schematic that may be useful:

**3rd diagram should be for your model
