I keep a 12v compressor, tarp, and a really nice plug kit my uncle gave me for Christmas in my truck. I can plug it and air it up in 20 minutes or so usually. I haven't put a spare on one of my vehicles since I started this program. I'll have to look and see what brand the plug kit is, I know he uses his at work for tractor tires and other equipment. It's all machined SS and much sturdier and nicer than your average WallyWorld plug kit.
