Install a Hunter Digital Thermostat in Your RV

                                  Out with the bad ...                                    ... and in with the good

An analog RV thermostat can be replaced with a Digital Hunter thermostat part number 42999(B) or 42995 to provide tighter temperature control in both heating and cooling modes.  The hysterisis program for the Hunter thermostat is +/-1 degree of set temperature, and also provides a digital readout of ambient temperature.   The Hunter unit can be purchased from Wal*Mart for about $20. 

I have also tested the programable Lux TX500 in my RV with the same positive results.  The Lux TX500 is available in many hardware stores.
