This is a great subject. I never thought about how long the AC would run just on lithium. It kind of changed my mind about cost for lithium vs AGM.
My wife and I do not have a Oliver yet. We have a Casita and we have been talking about upgrading. We carry a propane 2000 watt generator. It runs 16 hours. Our AC has a soft start so no issues running. We live on the east coast and very rarely need the Generator.
We spent one summer on the road in 2020. We plan to head to Alaska and Canada one summer. Would love to have a Oliver by then.
