I77 West Virginia/advice

Arrived on the 22nd of Feb. at the campground. Brought a filled 100lb propane bottle with me from home. The bottle is not empty yet. Gonna run it dry and just use my stock 30 lb tanks. Been running electric furnance and have heat set on 68 to 72. Furnance kicked on a few times when it was really cold at night. It's around 38 degrees now and furnance is electric fireplace is off. New camper is well insulated. Heated water hose hasn't failed but had to take off the flow reducer as it leaked and froze up one night. The water pump did spring a leak for some reason and replaced it. It's not used unless you dry camp so I could've just bypassed it with additional pipe. I didn't underpinn the camper and my black and grey water tanks did freeze somewhat. But on the few days it got above freezing they thawed out. Today will be a high of 38 and the temps are supposed to steadily rise from here on out. So all in all no problems in sub zero temps for 2 weeks!
