We have had ours for over a year and are very happy with it. It sat through last winter in -20° temps and this spring it still worked fine. Have at least 5K road miles on it and soon will add another 2 or 3K. Power wise, we do a lot of dry camping and the only addition we made was a 535A solar system 2 years before we changed to residential. We still have the same 4 battery house battery bank we always had and with normal use of all electric, we only have to use the generator every 3rd or 4th day to top off the batteries. Just wish we had made the change earlier, as it is nice to go to bed and not worry if the smoke alarm is going to wake us in time.....
