i have a 2610ML, the thermostat is located on the wall outside of the bedroom (when standing in the bedroom, on the right-hand doorway wall, outside of the bedroom. When the slide is in, the thermostat is hard to reach. Mind you, the thermostat installed on my trailer is one that does not go below 60F when in heating mode.

I do not know about the regular temperature sensor location in general. Would like to know where that sensor is.
