Keep in mind, you do not want to discharge below about 60% or 12.2 volts.
Run time totally depends on the load. If this (Harvest Host) is long term dry camping, then you will definitely need some form of charging capability either a generator or solar kit. If you'll have shore power where you are camping and just concerned about run time while you travel, then you should be OK since you'll be charging the batteries while you drive.
