RV Consumer Group uses both "motor home" and "motor homes" in its publications interchangeably to eliminate confusion; Motorhome Magazine uses "motorhomes" whether it's one word or two words, the meaning is the same.
At first, motor homes were called "house cars" (customized on model T chassis); then the name evolved into "motor coaches"and then to "motor homes". However, the motor home or motorhome concept didn't take off until around 1960's and 1970's when Winnebago promoted their motor home by dropping one on its roof. Whether because of this promotion, many people and far too many reporters incorrectly call all motor homes "Winnebagos" to this day.
The one-word "motorhomes'" came about when Motorhome Life was first published by Trailer Life Enterprises in 1968 as an annual buyer's guide. In 1982 the title was changed to MotorHome Magazine.
Although the one-word version motorhome is standard in Trailer Life publications, the two-word version "motor homes" or "motor home" is considered more accurate simply because dictionaries do not show the one-word version. This doesn't mean, however, that the one-word version as utilized by Trailer Life writers will not eventually be accepted by those of us who generally use the two-word version.
Whether you call them motor homes or motorhomes is irrelevant...we still rate them using the same criteria. Check our RV Ratings Guide CD before you buy one it will definitely be worth it.
