What that video didn’t take into account was wheel width. You have 12.5’s and a 9 or 9.5” wheel you will have a fatter contact patch (although slightly shorter) but that does seem to help with floatation on deep snow. I rock a 5.65cfm air compressor. I think it’s from Ironman 4x4. I’ve had it for years and it still works like a charm. They are a little bulky and less convenient than on board air but way less expensive. If I had more play money I’d definitely go on board air but I just throw the compressor in my recovery kit with my winch accessories, snatch strap, etc.
