Is your current thermostat a Dometic branded thermostat? If so, I would replace it with a digital Dometic thermostat. There should be a straight wire for wire switch.

It was for my Coleman thermostat.

My son in law and I have the same domectic thermostat for our AC/ heater and it is analog. we are thinking of going electronic or digital. what do you all recommend for the replacement?

I went with one of these...comes in white or black. Straight swap from the analog.

Call rvupgrades with your furnace and A/C info and they can get you the correct model for a wire to wire swap...
Works great. About a 1 degree swing for cycling. Also controls fan speed (hi or low)

As long as what you want to replace is not one of those cruddy priporatory things, then any self power thermostat should work well. I used a battery powered Hunter Douglas with great results. 25 dollars from WalMart. Much better that the wild swing one that came,from the mfg.

I went with the Dometic single zone Comfort Touch. Has worked very well for us.
