I dry camp about 50% of the time. One of the keys to dry camping is good batteries. Your question about how long will you have to run your genset is a little like asking about miles per gallon. Lots of variables. It will depend on what you use and for how long. Therefore I'll just tell you what I do. On inverter I run the lights, refrigerator, 110 air and water pumps, a computer and the entertainment center--tv surround sound dvd etc. If cold I run the AquaHot on diesel, but it does require 12V for the heat exchanger fans. Everything else I run on the genset. To charge the batteries I run the genset 2 hrs in the morning and 2-3 hours at night.

My Newell, with the series 60, has a slightly higher weight to horsepower ratio than my Cummins in another coach. The series 60 is far more responsive and powerful.
