Yes, it is very common to swap up to a higher BTU rated AC system and the Advent Air Replacement RV Air Conditioner for Dometic Setup w/ Start Capacitor # ACDOM150 will more efficiently cool your 2015 Forest River Salem Travel Trailer. This AC unit has a start capacitor included to jumpstart the AC when a campsite or generator doesn't provide enough power to start. It has an adapter cable to seamlessly connect to your Dometic system so that you can retain the use of your air distribution box and thermostat.

30amp service is sufficient to power your new 15,000 BTU AC unit. If you decided down the road to add in a second unit you would then need to either upgrade your trailer to 50amp service or supplement the power using a generator.
