We have a second air conditioner(Atwood 13.5K BTU Non-Ducted Air Command Air Conditioner)for our 36 ft. Motorhome that can be plug into 15 amps. Sometimes on the road traveling we have both airs going. My sister and brother in-law are now at the Colorado River in their 5th wheel and just recently took out their Fantastic Fan and replace it with the Atwood Non-Ducted Air Conditioner. They are really happy they did it. Our friends that spends 5 months in Palm Desert did the same thing, replaced fantastic fan with Non-Ducted Air Conditioner.
