Just found this forum. Recently purchased a 2014 Hartland Key Largo. Before that had a Sunny Brook for ten years, others before that. This is a first with a residential frig. looking to learn how to use this and keep the batteries up. Looks like many here will know. We dry camp sometimes and for as much as two weeks. We are real excited about this (new to us) fifth wheel. Looking forward to learning about this new adventure.
