There is no direct replacement for the Duo Therm model 57915.621. You will need to upgrade your entire system. I recommend the Advent Air RV Air Conditioner w/ Air Distribution Box, Start Capacitor, and Heat Strip - 13,500 Btu item # ACM135CH in white or item # ACM135BCH in black.
The units have 13,500 Btu will be plenty of power and the Advent ACs have a significant 500 cubic feet per minute of air flow. They have adjustable registers on the distribution box to help you control the air flow. The unit's start capacitor is also one of the reasons this is the best option because it will store energy, essentially giving your generator a power boost so you never have to worry about your AC not starting.
These units are designed for roofs that measure from 2-1/2" to 5" thick. I have linked an installation video below so you can see the process.
