Something else, I bought a Jackery 500 and a Twelseavan 120w portable solar panel for ours. We do boondock, but not a lot, mainly when we go to state parks. In our 174BH, the Jackery will run our little 8k BTU AC unit if we plug it directly into the Jackery. But the main reason I bought that is to run the Wagan Tech cooler I got. In our TT, the fridge is about the size of a shoe box and for anything longer than a 1 night, maybe 2 nights if we really planned well, so it just doesn't hold enough food for us. We are planning on a 10 day drip coming up this summer, so I wanted something we could actually store more food in, specifically a gallon of milk! The Wagan Tech will hold at least 6 gallons of the square Costco milk gallons.
But back to the solar. The last trip when we were using both the Jackery and the Twelseavan to power the cooler, the cooler was drawing about 55-60 watts most of the time. The Twelseavan was more than able to keep up with that. I think I saw it dumping about 72 watts into the Jackery at one point.
For our TT battery, I have upgraded to a 100AH lithium, but other than a cheap charge controller that came as part of a solar panel package I bought early on, I have no way to dump the power from the solar back into it. So far, it hasn't been an issue due to only short 2 night trips. Been looking at a Victron charge controller, but just haven't gotten that far yet.
Getting back into camping after about 40 years away. Luckily we are in the PNW and have a WIDE variety of places to go!
