I've completed three separate 3 night and 2 full day (+2 half day) boondocking trips in my 59k with solar in the last 30 days. I have also had to run the furnace each night except one as the temps were down to as low as the mid 20's. Still unsure of where 50% SOC is on the panels in the 59k, but I usually started the genny when voltage was indicated at @ 12.2v. According to manual, that should be about 50% SOC. If the day was to be sunny, I would run the genny @ 1hr+ in the morning, then another 1 - 2hr before going to bed. Never close to running out of propane.
What I found to be limited was the fresh water. Starting with full fresh tank (@25gal), and 7 more gallons in containers, it was just enough to last 2 adults and 2 large dogs for the trip. No showers were taken. Would be necessary to replenish water if a 4th night was in the plan. Actually, each trip has been 4 nights, only the 4th has been with electric/showers, sanitary station to dump and replenish.
Looking forward to our next trip next weekend. We've learned something on each trip.
Oh, BTW, my genny now has 20hrs (change break in oil) after said trips and @ 2 hrs have been test/practice run.
It's been very enjoyable for us, and many thanks are due all of you that have shared your experiences so that so much can be learned before you ever take the drivers seat.
