Okay I just checked... it draws about 2.6 or 2.7 amps, or 64.8 amps every 24 hours.
To replace 65 amps a day with a solar panel I would need at least the 120 watt panel shown here... and 9 hours a day of charging time.
Not a real pretty situation. So going rustic really means ice. The only other option I can see is charging the battery with the tow vehicle every day.
I've attached here a chart of solar panels showing both watts and amps. Never can seem to find that when I need it... this is from the
