#1 Have some family memebers with Traegers, I'm thinking about getting one "some day". They complain that they don't always get hot enough, especially on cold days, to rely on them as an only grill. You do need electricity too. So it probably depends on how much you grill. I'm sure it'll cook it until it's done, but you might not get the same results you're used to. You could always get a baby Weber Q or whatever they're called to bring out when you need it.

#2 Not sure but it sounds like the kind of thing you could either clean yourself or hire a professional to do. You can't be the only guy with an outdoor propane fire pit that gets clogged.

Good luck!
