Which of the RV's TWO A/C units are you referring to?
Both create condensate water in their cooling/dehumidifying process.
On our Ford chassis, the "Dashboard Air" drains from the passenger side front of the dashboard area, then down across the frame near the right front tire. This is Normal.
The "Rooftop Air" drains out onto the roof, and where it comes down, depends on how the coach is sitting. May run off a corner, and end, or a side. Again, Normal. The arrangement is common to "most" RV's, simply pouring condensate out on the roof. There are some with different arrangements. But, if it's cooling, and the condensate is leaving the cockpit or the house, without getting inside, it's Working!
