The Advent Air Replacement RV Air Conditioner for Dometic Setup w/ Start Capacitor - 15,000 Btu - White
# ACDOM150 will be the replacement AC unit for your 2003 Holiday Rambler. This unit will be plug and play with your distribution box and thermostat.

You will not need a seal, the # ACDOM150 comes with a gasket that goes between your RV roof and AC.
