Not mine!
Zone 1 is the front, 2 is the middle, and 3 is the rear.
I only have 2 AH zones, and on the single 5 button thermostat they are zone 1(front of coach), and zone 3( bathroom and bedroom).

One more wrinkle to note for on at least a lot of coaches of our vintage. On our '06 Dynasty, zone 2 on the rear thermostat determines what mode both the bedroom (zone 1) and the bathroom (zone 2) will actually operate in. If zone 2, the bathroom, is set for "furnace", and zone 1, the bedroom is set for anything other than furnace, the bedroom systems will not run, at all. If you want furnace heat in the bedroom, both zones on that thermostat must be set to furnace. If you want A/C in the bedroom, both zones must be set to A/C. Likewise if you want to use the heat pump(s). I don't know about the "fan" function, whether the zones have to match, but I highly suspect that they do. You can have whatever you want in the bathroom, any time you want it. But the bedroom is dependent on what you choose to do with the bathroom.

These thermostats are powered from and work thru the control boards on the roof units. The front roof unit is autonomous. The middle and rear units "talk" with one another which is why there are some oddities in how they are controlled, together.

My zone 1 is the front and has A/C, fan only and heat pump, no Furnace.
Zone two as the above and furnace and heats the front of bus (kitchen, living room and the center console registers with aquahot.
Zone 3 has same as Zone two and heats bedroom with aquahot.
Bathroom has its own switch on vanity for high low and off on the aquahot register, and I think it runs off the zone 2 or front heat, but it could be the zone 3 or rear I am not 100% sure.

You can reassign the zones with a little effort. I set the front as zone 1, the center as zone 2, and the rear as zone 3.
You remove the 4 screws holding the plastic AC shroud, then the 2 screws that hold the small metal cover over the control board to access the dip switches. With no zone dip switches on, it's zone 1. To designate zone 2, turn the zone 2 dip switch on and the same for zones 3 and 4.
After resetting the dip switches, you'll need to reset the thermostats. With the thermostat off, hold down the top mode switch and bottom zone switch and turn the thermostat on. You will see FF in the display.

Most Monaco coaches 40' and shorter have 2 zones. Coaches that are 42-45' have three zones.

The basement heat is active when thermostat is in Furnace mode. Many will set the furnace to 40 or 50 degrees for storage but that only works if you have 30A or 50A hookup when in storage. On my Coach the "Aqua-Hot" unit must be On for furnace mode to work.

On mine with 600D AquaHot I have to have the diesel burner on, just on electric doesn't do it. No idea why but that's what the manual says.
