KOA and Keystone RV offer a Cougar fifth-wheel and a decade of free camping in contest.

More than 3 million total entries have been received thus far for the “2013 Great KOA Giveaway Contest.”

The contest is sponsored by Kampgrounds of America Inc. (KOA) and Keystone RV Co.

One lucky entrant will win a new Keystone Cougar RV and a decade of free KOA camping when the grand prizewinner is selected in October, according to a news release.

The contest, which began in March, also includes weekly prizes of free weekends of KOA camping, portable grills from Weber Grills, and Cabela’s gift certificates.

“We designed this summer’s contest to entice campers to keep coming back and registering to win each week,” said Mike Gast, KOA’s vice president of Communications. “We’ve already seen 105,000 unique e-mail entries, and 3.1 million overall entries, and we still have four more months to go.”

The grand prize – a $40,000 Keystone Cougar RV provided by Keystone RV Co., and a decade of free KOA camping – will be awarded by KOA CEO Jim Rogers during the California RV Show in Pomona, California on Oct. 12.

“The huge number of entries in our Great KOA Giveaway contest reflects the public’s increasing interest in camping and RVing,” Gast said. “RV manufacturers, including our partners at Keystone RV Co., are reporting a strong increase in the sales of new recreational vehicles, and advanced reservations for the summer at KOAs across North America are more than 13% higher than the same period last year.”
