If you plan on boondocking carefully check out the house battery situation. At a minimum you want TWO 6V golf cart batteries, four would be better. Read this about charging your house bank while driving
DC-DC ChargingAgain, for boondocking, are you planing on a built in generator or smaller portable ? Personally, I would go with the smaller portable because a built in generator will take up a lot of storage space.
Last, also related to boondocking. What kind of inverter do they offer ? You really want and inverter/charger/transfer switch. No converter required. The DC distribution panel just attaches to the house batter bank with a fuse. Better ones have separate inputs for shore power, generator and solar. Inverter/charger/transfer switch means as long as you have adequate battery, generator or shor power, you will have both DC and AC power and the source will be switched automatically !
