This 20K includes the Re(Li)able Lithium option. The cost to me for the option  was $20,000.  Re(Li)able renewable battery system.                                                                                        (There are two lithium 5.5 watt hour for a total of 11 watt hours.)  It can operate the roof air conditioner system for over 9 hours.  

Because the lithium battery bank is so large there is no need for a propane powered generator.  The 11 kilowatt battery bank will charge quickly with one of two methods.  By a 30 amp plug “shore power”, or from a second alternator powered by the main engine while parked or while driving.
