Hello Sir, I have been following your posts and have enjoyed reading them. My wife and I have just started to look in to down sizing to a class B RV. I like what I see in ARV. We might be looking for a used unit as price is important. Can you explain the benefit to 48volt system vs 12 volt systems? What would be the difference for off the grid camping on two ARV's with 800 amp/hr battery's and 420 solar, one with 48v system vs 12v system. Thank you Kevin and Michelle Cook.
