just starting out full timing with no generator,or inverter.

Our 5er has Generator Prep, we held off buying a generator to see if we would actually use it and justify the cost to install and upkeep.
We have been fulltime almost 2 years now, only had a need for a Generator once in the last two years during a 4 hour power outage at a state park.
At this point we are still holding the generator money in my pocket. :)
