If you are wanting to change your 15k Colman Mach ducted A/C without changing thermostat, I recommend the Advent Air Replacement RV Air Conditioner for Coleman Setup w/ Start Capacitor # ACCOL150 (white) or # ACCOL150B (black). This system comes with all the hardware needed to use your current Colman setup on your RV. You will be able to use your existing thermostat with these models.

As far as changing your cover, these systems are designed to work with openings that are the standard 14-1/4" x 14-1/4. If your opening is larger than 14-3/8" x 14-3/8", you will need to install spacers between the sides of the unit and the opening's edges. If the opening is smaller than 14-1/8" x 14-1/8", you will need to enlarge the hole to fit the unit snugly inside the opening. In order to determine if alterations are necessary, I recommend measuring your current opening that you use with your Colman model.
