Consider this.. They are not so "smart" when they fail.
RV smart locks have a pretty bad reputation for failing and when they fail, it is at the least opportune time.
Security cameras on a RV? Gonna have to bring your own "Internet" with you, that is going to be a huge data bill and if you camp in places where cell coverage is not so good most likely will not work..
Internet T' Stat, why bother, a RV is very small, takes you a whole 1 minute to walk front to back and just seconds to reach between the side walls..
Leave your "Tech" at home and enjoy the simpler life of being "unattached" to the Matrix..
