A lot of the reason for noise is needing to use a small fan to move a ton of air. This means high fan speeds and high noise. There actually is a correlation.you can get a 9000 or 11000 BTU roof unit in the high profile.
Coleman Mach 48207C966 I Power Saver RV Rooftop Air Conditioner - White - 11K
The Coleman Mach 1 Power Saver is an air conditioner designed to use less power without sacrificing cooling performance. To get more cooling with less power a high-efficiency compressor, a high-efficiency fan motor, and over-sized coils were matched to maximize cooling and minimize amp draw.www.rvupgradestore.com
I think the profile has little todo with noise level. When you look at the specs - there are also high profile which are loud It's more like that one manufacturers low profile are loud.

The issue you're describing is the manufacturers just not giving a damn and still using the same small fan, or one that's only very slightly larger with improves very little.
