These are my definitions of fulltimers, part-timers, snowbirds, some-timers and campers.

Fulltimer - Someone who lives "and" travels full time in a recreational vehicle (RV). A fulltimer normally does not own a house or condo.

Part-timer - Someone who travels six or more months a year in a RV, then returns to a home base such as a house, condo or apartment.

Snowbird - Someone who generally lives in two places a year. A typical snowbird lives in a house in the northern states during the warm months and in a RV in the southern states during the winter. Some snowbirds do not own a RV and spent the winter in a condo or apartment. Also, some snowbirds live fulltime in a RV but only move it twice a year.

Some-timer - Someone who uses their RV for weekend get-a-ways, vacations and sometimes month long travels.

Campers - Campers are usually young people or families who use RVs or tents for weekend or week long camping. Many carry sleeping bags, coolers for food and build nightly fires.
 

We sold our house, furnishings and cars and live and travel fulltime in a motorhome so we are fulltimers. Most of our traveling friends are also fulltimers. During our nearly eight years we have visited 44 states, 9 provinces in Canada and crossed into Mexico two times. We have also spent the night in about 480 places. Shortly after starting our fulltime adventure we met a couple in Clarksville, Indiana who said they were also fulltimers. They were living in a travel trailer but had been in the same campground and campsite two years. Both worked fulltime jobs and they were trying to save enough money to hit the road again. Even though they considered themselves fulltimers they did not meet the criteria for living "and" traveling fulltime in a RV.

In Tennessee we met an interesting couple in their 70's who had been traveling many years. We asked them if they were fulltimers and they said "No." They had a home in Florida and only traveled eleven months a year in their motorhome. Then in Oregon we talked to a man who said he was a fulltimer. He lived in a fifth wheel and worked six months in Oregon and six months in southern California. He was considering selling his truck and having a tow company transport his fifth wheel back and forth every six months. That man was definitely not a fulltimer as he did not travel in his RV.

We have friends who have spent the winter months in the same park in Arizona for many years, but they travel around the country the rest of the year. Yes, they are real fulltimers. Even fulltimers have a need to sit in one place for several months. The difference between fulltimers and part-timers is fulltimers can spent several months in any park in the country while part-timers return to a home base.

The above categories of RVers get along great except some of the campers. Many campers keep a fire going day and night and keep the campgrounds filled with smoke. There is nothing we hate more than having our motorhome filled with smoke from inconsiderate campers. Often the children of campers run through our campsite and play ball games and frisbee within feet of our motorhome. Luckily, campers are only out between Memorial Day and Labor Day. The other nine months the campgrounds belong to us. Before becoming fulltimers we were tent campers who traveled in a van with the middle and back seats removed, so we understand campers. 

Fulltiming is not for everyone as many people have a need for a home base or somewhere to return every so often. We have given our definitions for the categories of RVers, but it is really just a state of mind. And we don't mind if someone has not moved their RV in many years, owns two houses and claims to be a fulltimer.
