I grill in all weather. Grilled in typhoon, monsoon, blizzard, and -13*. Gas is good. Charcoal has its place, but gas is quick and clean.
I'll go down and start the grill to let it get hot, then go back in to the kitchen to start working with whatever I'll be grilling, e.g. making burgers, fooling with the chicken, slicing pork chops out of loins, seasoning, tools, etc. Budget about 7-10 minutes, depending on outside temp.
I grab the meat and the tongs and go out to the grill. The grill should be hot (400*) and be burning off the stuff from the last grill session. I don't pregrease the grates, I just put the meat down and char it. When it's ready to turn it will have already released or will be easy to release.
Crosshatch pattern on both sides. Cook hot, cook fast...outside cooked quickly, inside tender.
As mentioned before, have at least one extra bottle standing by to replace when the one in the cooker gets empty. It sucks when the grill stops in the middle of awesome pork chops or steaks. I have always tried to go to places that refill bottles, but now I simply exchange bottles at the local Home Depot. They're open about any time I might need a bottle.
Enjoy your new grill, OP. You're going to love it.
