We spent last winter in Baltimore Maryland in a CG on the Bush River, which is a body of water that flows into the Cheapeake about 20 miles north of the city. We had temps from single digit to 40 on average, I would say 50% of the days were above freezing, the nights were usually just below 30'f. Here is how we handled the cold.
We installed a "extend -a-hose" for the propane tank, then purchased 100 lb bottles from the CG, $81 per bottle. My wife is very, did I say very, conservative on using the propane or electricity. She was here by herself 85% of the time. She would turn the heat down when she went to work to about 60'F, then back up when she came home to about 68'F. When she came home she would turn it down to 50'F. She & I would only turn on the hot water heater which is only propane, just prior to needing to use hot water for shower or dishes, usually done at the same time, then turn off after shower. We would leave the cabinet door open to remind us it was on. We do not have basement heat or heated storage tanks. We went thru a 100 lb tank every 10 days.
We purchased a heated potable water hose by Pirit
Pirit Heated Hose-The Only Cold Weather Heated Hose. This hose gave us no trouble at all. However the water gets a slight rubber taste so we used bottled water for drinking. I insulated the faucet with foam pipe insulation & the cg insulated the other end of the faucet & water pipe with heat tape. I purchased a insulation blanket about 5-6ft long by 1 1/2 ft wide & stuffed it into the water service bay. This blanket helped but was not enough, I had to install a 60 watt incadesant trouble light in the bay also. we never had a frozen water line after that. If you do this be careful that it hangs without touching anything in the bay, even though it is in a cage type holder I worry that it could melt plastic or even cause a fire.
Our hot water heater is in a closed compartment under our bathroom vanity, I removed the panel that accesses the tank & plumbing & left it off. This did 2 things, 1 this area would be at room temp when the tank temp was nuetral & when the water was heated the heat would radiate into the bathroom area a little. we opened the cabinet under the kitchen sink at night also. When we left for extended times 2-3 days we would shut off the water outside at the faucet.
We found that the dash area & the slide area would be colder than the rest of the MH & even have some drafts. We placed 2 20'f sleeping bags over the dash to the floor covering the engine doghouse. On the side walls we placed our camping self inflating sleeping pads against the sidewalls. Now these didn't fit tightly but you could tell they made a difference. I would think some of the styrofoam 1" or 2" boards form Lowes would do the same.
Then we also used quilts just like as if we were in our stick built for this time of year. We made it, it wasn't the best of times, but you do what you have to do. I have seen some RV's with underpinning wrapped around to keep the wind from coming under the rv. We didn't go that far, thought about it , but decided against it, not sure the cg would allow it either.
By the way the CG staff told us we had the cheapest electric bill of the whole cg each month. They were surprised. We were happy.
