YES you NEED to have your dogs licensed/rabies shots--certificate and that would be using your Lancaster OFFICIAL address like on your DL
How many dogs...........as per LA County Regulations since you are an LA County Resident
YES your RV is your 'home'-----place of residency is LA County---but RV is your 'home'
Staying at friends property and LIVING in the RV.
It being LA County I highly DOUBT you can do so LEGALLY
LA County (California) frowns on 'living in RVs' unless in commercially developed, regulated business ---IE: Private/Public Campgrounds
