Looks nice but 1000 watt max will probably only get you about 16 miles per day or slightly more in average to good sun, depending on how one could manage the array orientation or tracking. Might be substantial enough for some I guess if they planned on parking at a camp site for one to two weeks before moving on. Range of course would depend on the average driving speeds too.
Other than that it's a good supplement for typical camp site use more so than significant charging.
