Barb, I've smoked ribs on my gas grill....no babysitting necessary. I put my soaked wood chips in a foil pan, sealed with foil and holes poked top and bottom. I put one side of the grill on high and left the other side off. When my wood was smoking I turned the heat down low and added the ribs as far away from the heat as possible and closed it until the smoke ran out from my chips, probably about an hour. My seasoned ribs were cooked but not really tender, needed some moist heat for a bit, so I sealed them on an old sheet pan, added some orange juice and sealed up tight, cooked over a low flame, turning it off and on a couple of times.
When tender I finished them on the grill grates with some sauce....but you could so whatever you wanted. I just played around with it. I'm not a huge fan of a lot of smokey flavor but prefer just a whif here and there.
