Hi guys new to the forum (wish I had found it month ago). I'm out in Utah I've been trying to build a medium size offset smoker for a couple months with no luck finding and good/cheap propane tanks or otherwise. Last weekend I got lucky my friend gave me his 120 liter type 2 CNG cylinder, it measures about 48"x16". The issue is I've only ever worked with LP tanks and don't have any experience with CNG. So any tip or tricks, does and don'ts, will be greatly appreciated. P.S. From what I've read the tank is reinforced with some sort of non-metallic outside liner, what would be the best method for removing that, or should I just keep it on?
