There are three types of thermostats
one uses a mechanical make/break switch. You can see the contacts open and close. A small magnet provides some Difference between make and break temps
ACE Hardware (As I recall) or True Value (If not ace) sells one for 20 bucks
These work on both 750MV 12 volt DC and 24 volt AC, all the same it does not care.. It also does not need to be perfectly level making it ideal for RV use.
The second has a liquid (Mercury) Filled capsule on the end of a spring, the weight of the Mercury (liquid metal) provides the difference between Make and Break.. Like the above it works on all systems. UNLIKE the above it must be leveled else the settings will be off.. I do not recommend for RV use
The third is Electronic. This type is system specific, I do not recommend.
