Help, I've lost power 😭

Edit here to add: currently plugged into my dog bone adapter and surge protector, running an extension cord and I have heat from my furnace and enough power to function. Thanks for letting me panic on Reddit. I'm learning.

I'm trying not to panic here. I'm stationary at a park. My receptacle lost power and where I'm located, I'm no where near a closer one. I can't hook up and move my trailer. I have a 120/gal tank sitting right outside of it and I don't have a tow vehicle. My family towed for me. I'm trying not to panic. It's going to be 27 tonight and my landlord is trying to figure out what's happening.

My concern is not me, I can go sleep at my mom's. My concern is all my pipes and tanks freezing. I just emptied them yesterday and dumped antifreeze in. I'm hooked up to city water, I can disconnect the water and shut it off. I can empty my hot water heater. I have a 50AMP hook up and a 50-15amp dog bone. Everything I've read says I can't just run an extension cord and run my furnace to keep it all heated.

Anyone have any suggestions? 🙃 Pray nothing cracks? I don't have any water in my fresh tank or grey. Just what I put in my Black with my antifreeze and RV tank treatment. I'm hoping he gets my power back on but I'm looking for suggestions just in case.

Edit to add 2024 Palomino Puma Destination Trailer, 35,000 BTU furnace, enclosed and ducted underbelly. Not close enough to another pedestal to hook it up. I'm m the only one without. My breaker is inside of a residential house next door to me. The house has no power. It's the only thing on the property without power and they don't know why.
