Lithium batteries have some advantages. First you can run them down to 20% where it is recommended not to run AGM past 50%. Consistently running AGMs below 50% will shorten their life appreciably; Lithium have a life expectancy of 10 years. But perhaps one of the most important aspects is weight. Some suggestions have been to add more batteries to increase you staying power while dry camping. Before adding additional batteries determine where you would locate them. Adding additional batteries at 75lbs. each can overload your axle end and/or unbalance your coach to a point where safety is an issue. I have weighed a number of Motor Homes that exceed axle end weight and batteries are usually at the root of the problem. Overloading an axle places excess wear and tear on suspension parts, brakes, steering and tires, all contributing to safety issues.
