I'm referring to those that buy a unit and think they will only camp a certain way (i.e. only in resorts or full hook ups). Over time, many change their attitude over how they camp. What they think they would never do one day, they end up doing it later. Not all RV's are good for all situations (in the way they were built). One who goes into a resort setting is not worried about size as mostly any size unit will fit. However, if they decide to go more rustic to places where site sizes are limited, then they could have an issue. It also goes with tank sizes, batteries, solar, etc....
