⚠️ Before You Order

Rooftop unit only — a ceiling assembly (ducted or non-ducted) and thermostat are required and sold separately; if you're replacing an existing Coleman-Mach, your current ceiling assembly generally carries over. Fits the standard 14" x 14" roof opening. Units ship with the roof gasket pre-installed, so no additional sealant is needed. Confirm your RV's electrical service can carry the unit — the Power Saver models are the choice for 30-amp sites and generators.
