There's absolutely no fiddling.
You will likely need to get the thing connected by a licensed gas fitter. In the spring or after a long rest, you're supposed to check to make sure that spiders haven't nested in the burner inlet tube. (This is true as well for propane.)
With propane you'll want a second tank so you donpt run out mid-cook. Even with a spare tank though, when it runs out you usually don't notice until the grill starts to cool off, and screws up your timing.
For gas grills, I'm 100% on the natural gas side of the fence.
