Why would you care how precise it is? Just turn it on, and bump it up or down a degree or two until you are comfortable. Maybe even make a pencil mark on the thermostat when you find the sweet spot. Use the on/off switch and don't touch the adjustment again.
Our experience has been that there's not one good spot anyway. Even a digital thermostat with 0.001% accuracy won't do. Here are some reasons why:
1) Humidity. Your temperature sweet spot varies with humidity. When everyone's been breathing all night and the humidity soars, you'll be comfortable at a different temperature than when you've aired out the unit and there's just one or two.
2) Heat/cooling varies across different regions of the trailer. It's especially evident in our 38' destination trailer. The furnace is located near the bedroom at the back. If we leave the thermostat at the comfort level for the living area at the front, we roast at night. The air conditioner is at the front, so the bedroom is hotter than the living area when it's operating, too.
