I think a lot of reviewers here don't have enough experience in pellet grilling to recognize how many features are packed into this unit for the money. I'm not going to talk about the usual advantages of pellet grilling in general in this review (i.e., clean flavor, "set and forget", less ash,). Instead, I'm going to focus on what makes this one uniquely better than the other grills in it's class.
Still loving it after cooking about 100 meals. Thru rain, snow, and the occasional nice day it is still going. Today I'm about to grill brats. My weber grill sits around rarely needed so it's going to get sold. I discovered with quality pellets it can grill just fine to temps up to 450. The camp chef grill cover keeps the pellets dry in the hopper so I don't even take them out unless you want to change flavors. I did have to seal the hopper handle around the rivets to keep the rain out but other than that it is very tight. See the pic makes smoke like crazy.
The SG and ZG are not exactly the same though. Just from the pictures I can see that the bases are different. The SG has L-shaped legs and a bottom shelf while the ZG has square legs that are larger than the DLX legs but no bottom shelf. There were also different specs for many features. I took a picture of the ZG spec sheet at the store and compared it to the SG specs on the website and there are slight differences in capacities. For example ZG 3778 cubic inch - SG 4859, grilling area ZG 776- SG 811, hopper volume ZG 18 lbs - SG 22, ...
Pellet grills preheat quickly, so you can start cooking almost immediately, and the pellets are available in a number of woods, for different smoke flavors. The smoke has a subtle wood-fired flavor with less of the acrid flavor that comes from standard wood or charcoal. For the maximum smoke flavor, it’s best to cook at a temperature lower than 250 degrees, while higher temperatures cook faster with less smoke.
