I have the Q100, removed the regulator and put a quick disconnect to use with the Jayco's LP outlet. At the house I ran a line to plug it in there also, and also have a regulator and quick disconnect on a 20 lb bottle to cover all bases.
Really like this grill, I originally bought it for a temparary replacement when my house grill's burner burned out. It worked better than the big one, and I use it for everything now.
Mine didn't have the temperature gauge, went to Home Depot where they had the replacement Webber gauges. Drilled a 1/4" hole and installed it. Nice to see what the temp is inside. Doesn't take long to get it to 400F.
