and a little rum :-P
RV= Recreational Vehicle..it encompasses ALL types. RV dealerships, motor vehicle depts (Along with other gubmint agencies) and, unfortunately, Home Owner Associations generally use this term as generic.
Camper (Or truck camper) = That thing in your truck bed that you can take out and sit somewhere..or not, depending on your preferences.
Pop up Trailer = that hybrid canvas thing with beds and stuff that sits on a trailer frame.
Travel Trailer, or Trailer Coach = That crunchy sided thing with beds and stuff that sit on a trailer frame. (Includes Teardrops) Can sometimes be a hard sided Pop Up, like an Aliner, or not, depending on where you are.
ARE WE GETTING CONFUSED YET?
Motor Home (Or Motor Coach) = That big box that sits on, and is permanently attached to a motor driven chassis. Motorhomes have their OWN categories.. Class A and B, B+, C and "other" depending on someones imagination. Buses are Class As'. Some class Bs (Van conversions) are simply motor vehicles, depending on how they are titled..a "Ford" VS a "Carefree" etc.
No wonder DMV employees (And former RV Dealership
Title Clerks like me) are grumpy.
They are ALL RVs. Just RVs.
