Some people may think full time RV's are transients.
The dictionary describes a transient as an individual traveling about looking for work. The vast majority of full time RV's are retired individuals who worked most of their lives and now are looking to enjoy our beautiful country.
Others may consider full time RV's as gypsies. The dictionary describes a Gypsy as a member of traditionally itinerant people.
Itinerant doesn’t describe an individual traveling about in a RV that can costs as much as some homes.
Now the dictionary describes a Nomad as individuals who do not have a fixed residence and moves about. That comes about as close as you’re going to get to describe a full time RV'er.
