I never considered my OSB BOX a bug out trailer but last summer as the forest fires raged and we were on evacuation alert... that trailer was ready to "bug out". Thankfully we never got the order but we hosted lots of campers forced to abandon their homes who were only a half hour south.
Had the opportunity to camp at a work event (that's rare, right?) Brainerd Raceway in Northern MN. Not exactly off grid, but an excellent testing opportunity. Unfortunately, solar panel underperformed all weekend. I was definitely facing North, but I feel like it should have done better. Was down to 11.6 volts and fridge was even pissed off. Will do some testing before end of the month trip.
