The invitation-only 2012 Road to Ram Jam concert in Nashville just got much, much more interesting. This month, Zac Brown Band were announced as the fourth act, joining previously-revealed Easton Corbin, Brantley Gilbert and Kellie Pickler for the Dec. 29 show. Here, you can enter to win a free trip to the show and some great gear from Ram and Zac Brown Band.

As part of his performance, Brown is driving a 2012 Dodge Ram for the entire year. Then, he'll auction it off to raise money for Camp Southern Ground, his planned 500-acre camp for kids with and without special needs. In a new video, Brown talks about his commitment to children, and how Camp Southern Ground is his life's work.

"This camp's about making sure that my life meant something when I'm gone," Brown says. "It's real personal to me." Ram has even donated vehicles to the camp, which is something Brown really appreciates.
