They shouldn't be on the stat if they are not on the trailer. Turn them on and see if you start getting warm air from the vents. Not sure if heat strips are in the A/C or an electric option on the furnace but select them and ste the stat temp high and see what comes on. As I said above all these electric head devices are running up the cost of RV sites, propane is much cheaper and more efficient.
