Water Leak In A New RV, What Should I Do?

Definitely a warranty issue and although one here advised to check your seam calking twice a year, having purchased yours October 2012, is too new and should never have had a leak. The first year ours was idle through the winter, I continually went out and checked the ceilings for evidence of a leak and continue to do so each winter. Same with the calking. Call your dealership tomorrow without delay and get it in. They need to do a thorough inspection to make sure they've isolated the leak and the damage. Good thing you caught it quickly.
