I am familiar with a NEST thermo. The color of the wires on the RV should conform to AC standards of which there are none.

Power to the device is a serious consideration. Contact the manufacturers support BEFORE purchasing. Discuss their product in your proposed application.
The residential standard power is 24 vac. If your RV provides this voltage, then installation is straightforward. The NEST may have a solution to this if it is a problem in your application.

With the problems involved, I would have to recommend the PROFESSIONAL installation option mentioned in the NEST directions. If you have the tools, skills and knowledge to resolve any issues then do it! I can vouch for the NEST thermostat's durability. It has been subjected to rough handling, changing homes and power outages.

I love my NEST and it is much smarter than needed but I can check and set it from any internet access. Nest Learning Thermostat 3rd Generation Stainless Steel Works with Amazon...

I'm guessing your blue wire is your common and red is hot. You need a voltage meter. Should have 24 volts with R&B. If not either you blew the 5 or 3 amp fuse when hooking up or your wiring is wrong. If there is an outlet close you can test red to ground and see if you have 24. If you do have 24 blue is either not common or its unhooked or shorting on something. Good Luck!! Fuse would be internal , car style, turn power off and open furnace to inspect.

Remove the thermostat from the system (just remove the R wire from the circuit board in the FAU) and see if the problem continues. If it doesn't fix it, the circuit board on the furnace should be replaced (something would be seriously wrong with the controls). If the problem stops and you have a nest thermostat (they do this kind of thing often) talk to Nest customer support, they have a solution using a capacitor. If you dont have a nest, replace your current thermostat as it would be faulty.

Do you have a common wire? The nest thermostat needs the common 24V C wire installed to keep the battery charged fully. Nest should tell consumers of this problem, but they don't. Its required for any powered thermostat. Even the new fancy Honeywells with touch screens etc..

Gotta realize the battery cannot run the display and wifi plus all the sensors for very long.
