The house batteries on my new2017 Vegas rarely show above 2/3 charged. Usually after running generator (use/store switch in "use") for a short time they will read fully charged but shortly thereafter back to 2/3rds. Is this an indication of maybe something drawing power off of them while sitting in driveway? (Switch back to "store"). Thanks for any help/advice.
