I agree with driftwood. I had my Host out a few weeks ago in SE Utah. No cell service and way out we lost our batteries in the night. 3 am alarms started going off for low voltages. A long night story shortened, I bought a phone card, and from a pay phone called Host and asked about an inline fuse possibly buried in the harness. Trouble shot the regulator in the solar controller as bad. They are and have been very helpful.
Welcome to the forum! By chance are you the Host owner storing off SR.Ave? Used to park my 5th wheel in adjacent yard.
