Is the trailer 30 or 50A? What "breaker" tripped; inside the trailer or the one at the power ped feeding the trailer? Do you have an EMS in use, if so what does it say on the incoming power? If the gfci won't reset it tells you that there is probably no power coming to it (it won't reset unless there is voltage there) and one side of the trailer with no power says you possibly lost one leg of a two leg 50A circuit. Your furnace, thermostat and control board operate on DC current not AC. If your batteries haven't been charged by the converter due to loss of that leg of power they won't operate the furnace etc. You need to do some further analysis on what your incoming electrical looks like. Do you have a VOM and know how to use it? They are invaluable.

Also, model number of trailer, so you have a better chance of getting a response from someone who owns and has experience with the same one you have.

I have a 25RES Cougar with an inverter issue. When plugging AC in and out plugs into inverter the breaker in fuse box blows which is labeled solar but also has the inverter plugs in rv attached to it. The inverter has been replaced with the same symptom with the new one. Without a wiring diagram I do not know what is hooked into this breaker. All of the inverter plugs are empty and no load. Can you help with this problem and is there a wiring diagram available? tThis is a 2023 model with the 200 solar system.
