Will getting a larger roof A/C solve the problem?
I have a 1993 Winnebago Brave 27RC and it has a coleman roof A/C. The BTU's are about 12,500. If I install a 15,000 Coleman roof A/C will it stay cool better in the hot Florida summer afternoon?

Have you looked at all of the ducts and return air divider? My 13,500 and probably most ac units have a piece of cheesy baffle between the intake and outlet sides of the ac unit. When you remove the grill you will be able to see where the cool air comes out and the warm air goes in. The tape was falling apart in mine. The other thing that I found was the tape was deteriorated at the outlets and blowing cold air into the ceiling/roof cavity. I used spray foam to seal those areas but be careful or it may flow out and drip onto the floor.
