Do you get a housing allowance from your company? My Dad's home care nurse (after hip replacement surgery) lived in an RV as she had the same sort of gig - go where the patients are. I wasn't there the day they were talking about this and don't know the specifics of what she had, though!
Before I offer an opinion...How many dogs? Are you the only human? What kind of car do you have? Do the dogs need to be separated during the work day? Are you physically able to climb a ladder up to an overhead bunk? Not all cars can be towed easily...
