While I do NOT have your model I do Have a Leprechaun. That said I see a Window aft of closet and of course possible roof seals need inspected. Water most likely is not coming in where you see it and possibly is running down a seam line for several feet before finding a way out. Suggest after you inspect yourself if able to consult your Coachmen Dealer following that since I expect there is still a warranty. Some shops have a device where they pressurize the RV unit and with soapy water 9like looking for a tire leak) go over the entire unit looking for leaks.
With that exhausted consider contacting Ron Ross at Coachmen 574-825-8602 firstname.lastname@example.org
for answers or even repair if your willing to take trip to Middlebury, Indiana.
I had a bunk leak that needed extensive repair so I left it there four weeks. While it was there I recalled a minor window leak by bed that I knew I wanted to address so called Ron asking them to check it while they had it. My minor window leak was repaired along with interior wall panel replaced because of damage they felt needed addressed.
What ever you learn or choose to do act quickly to prevent more damage.
I can and will speak HIGHLY of the Coachmen Class C people at Middlebury. Be prepared to leave unit if you go this route. This is a factory not a dealer so drive in same day repairs are unlikely. I feel they have a harder time being upfront with time line and to communicate work scheduling than even a dealer. From what I some have very lengthy repair experiences at their dealers.
I wish you a speedy fix.
