Will a heater in the living space protect the water lines and tanks? I have a NL 9.5 and don’t thinck the heat will reach the basement.

If your basement isn't heated you could do what Arctic Fox did on our old camper. install a small electric fan that forced cabin air into the basement and a second hole with grill to allow circulation back into the cabin. You would need to cut a couple holes with a hole saw drill bit in appropriate places, find a small 12v fan and a grill.
