I guess I know the indoor storage is ideal but can I get away with the other method. Thanks in advance for any advice.

Your Newmar is, or should be unless someone changed it, equipped with a charging system that will maintain your Chassis and house batteries as well or better than any off the shelf maintainer.
It sounds like you have access to a 15A service plug so, the coach in, leave the chassis and house disconnect switches ON, turn the gas detector off and your in business.
Check the water level of the house batteries every 6-8 weeks to make sure they don't go dry. Check the battery voltage while plugged in. It should not exceed 13.8VDC.
My coach has been plugged in 24/7, unless we are traveling, for years. The batteries are approaching eight years old.
