The tiny desert town of Quartzsite, Ariz., located just east of the California border, is preparing to mark the 30th anniversary of its annual Sports, Vacation and RV Show, which promoters claim draws the largest crowds of any RV show in North America.

According to a report by RV News Service, the show takes place in and around a 70,000-square-foot tent a half mile south of I-10 on U.S. 95. This winter’s event runs Jan. 19-27. Admission and parking are free. The attendance for the 2011 show was estimated at well over 100,000 with more than 400 exhibits inside the huge tent and surrounding it.

“There will be hundreds of new and used RVs on display in 2013 and over a dozen service bays will be offering immediate installation, repairs and service on many of the items that will be exhibited at the show,” said promoter Kenny King.

Many tourism-related exhibits from the United States, Canada, Mexico and Europe will be on-site, as well as representatives from dozens of RV resorts and campgrounds. Some will offer information about seasonal job opportunities for “workampers.”

While some of the RVers who visit the Quartzsite show stay in local RV parks, most hole up for free on government lands just outside the small town. Information for visitors and exhibitors is available at www.quartzsitervshow.com or by calling (714) 377-7940.
