Not sure what hoops having a fridge is jumping through. I plug the fridge into the 12v on the Bronco and go. While I am driving the fridge is running and the integrated battery is charging. After unplugging, the battery will run it for 8 to 24 hours. When camping with my Aliner, fridge plugs...
I have nothing to do with Kenda other than running them on my Bronco. They last well, balance great, are super tough in the Arizona rocks, good in mud and snow, and are very quiet for RT tires. Also great pricing.
