"Most of the jobs on offer are from hotels, amusement parks and campgrounds. With the supply of seasonal workers limited in many rural areas, some employers have been pushing to draw RV-dwelling workers.

Last year, for example, Kampgrounds of America Inc. launched an incentive program designed to attract working campers, offering them free nights at member campgrounds as they motor between jobs, as well as discounts and sweepstakes drawings.

Managers at Adventureland, an amusement park outside Des Moines, Iowa, also have recruited RVers. Until five or six years ago, virtually all the park's seasonal staffing was done locally, and included mostly younger workers.

This year, about 400 of the 900 employees are RVers, most in their 60s, a boon for a park that was increasingly competing with retailers, casinos and other businesses for local employees. The older workers often arrive with an optimistic attitude and better work ethic than younger workers, said Steve Anderson, the park's personnel director."
