Is your trailer a Jay Flight? If so, unless Jayco has changed, you will find a analog type thermostat on the wall.
My 2017 Jay Flight 23RB came with the non digital Coleman-Mach thermostat. I quickly replaced it with a Coleman-Mach digital thermostat. The new thermostat keeps the temperature within a 2 degree range. On heat if 78 is set, when the temperature falls to 77 degrees, the furnace kicks on. When the temperature gets to 79, the furnace cuts off.
In the past, my trailers only had heat on the thermostat. In those cases I just replaced with an inexpensive Honeywell thermostat from a big box store.
However, my current trailer has central heating and A/C. Too many wires to have to deal with if attaching a residential type thermostat. So I paid the extra money and got a Coleman-Mach digital thermostat. This way, it was just a straight swap, wire for wire, from the non-digital to digital thermostat.

I have a real aversion to the non-digital type of thermostat and hope that my new tt has a digital type. Does anyone know what the 2019's are coming off the line with?
