My old TT had the, pain in the nec, 4 knobs to unscrew, and cover to pull off, just to turn gas on and off. Currently just have the flip top lid, so it's much easier. I've always left gas on when camping and driving, and getting gas. When it's sitting in the driveway, gas is off. One of the kids (or me) could accidentally bump the stove or kick on the HWH and create an issue. I do agree, that there shouldn't be leaks, so technically, yes, you can leave it on all the time. Also, I remove my 2x30lb tanks and figure one less thing for someone to screw with when in storage away from home over winter.
