FYI Heads up.
Regarding the Coleman Road Trip Grill. It's regulator lets so much gas through so fast at start up, that the Propane pressure safety line shut off will trip very easily. I learned this after thinking I had run out of gas once and trying to get a new tank full to replace a tank that was full. Luckily the Hardware Store that was helping me diagnosed the problem.
Once you connect the line to the Grill regulator, crack the tank valve very slowly. Let the line come up to pressure and then open the burner valve and try to light, let the air bleed out and continue to try and light.
The tank safety valve is very touchy, and you may need to repeat. Once you have the grill lit and running full flame, use as normal, shut the flame off at the burner control, but do not shut off the tank valve, let the line remain pressurized and you should have no further problems until you have to change tanks or remove the tank to pack up and go.
This is a characteristic of Coleman Grills as they have a much higher BTU output than most normal grills. Almost double some of the common every day grills.
I learned all this from the owner of the Hardware Store in Lugoff, SC. I guess old fashioned hardware stores still have their uses.
