15k AC Question

Having just spent a week in a warm Northern California, 50 miles north of the Redding fire, on 20 amp service, in my Open Range Ultralite, It worked great. As others have said, no microwave and A/C together, and you'll be fine. Glad we have the 15k. It would have been toasty with anything less. We love our Open Range (Highland Ridge). We're re-doing the master bed and bathroom and are sleeping in ours right now, in 100+ temps in Fresno, on a 20 amp circuit. No problems until the wife plugged the iron into a plug on the same circuit. Popped the breaker. No regrets with our purchase. The two year warranty is good too!
