Freeze prevention ?

Thanks for all the great input and suggestions, I’ll take some of what will work for us and hope for the best. Just arrived and opened the camper up. No problems found other then an icicle hanging from the one already opened low point drain. First ran the furnace and fireplace to get the coach up to 60 from 38 when we arrived. Hooked up to city water first then checked for leaks, none. Ran HWH on both gas and electric together to get hot water, no problem. Filled the fresh tank until full and checked all faucets, no problems. I layed a couple thick blankets over the outside kitchen faucet inside the cabinet to hopefully help. Current temp is now 31 from TWC, forecast low of 19 tonight high of 38 tomorrow and overnight low of 25. Should be ok. Love the electric fireplace and still running the LP Furnace to hopefully heat the underbelly.
Surprisingly the above ground campground water faucets are not frozen. I see several units that do like we do for football season that still have the water hose connected to the side of there rigs. At least I disconnected it and opened low point drains. I am noticing the larger Class A motor homes are doing what I’m doing for the night,
Unit will be winterized by me next when temps are forecasted to be near 50 daytime and overnight in 30’s
Thanks again for the suggestions.
