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, ...
Bought the Costco trade show model after about 4 years of debating the purchase... OK, first one broke on day one as "auger" stopped spinning. Returned and received a new unit. 2nd one smoked a turkey for 4.5 hours. After 4 hours temp. dropped to 100 degrees and it was set to 350. When I opened the smoker to check on why this happened, it exploded into a ball of flames! There was fire shooting out from all sides of the grill and smoke and heat coming from the feeder side of the grill... This was SCARY and could have absolutely caused a major fire, and/or injury!!!
Access to electricity has its downfalls. First, if the cord isn’t long enough you will need to make sure you have a proper extension cord. Using the wrong cord is a fire hazard. Do the math (watts / volts = amps) and make sure you have the right extension cord. The smoker is also less mobile, and if it's stored outside it absolutely must have a cover. Electrical components and weather don’t mix.
2. The grill does not come back to the set temperature after the lid is opened and closed to place the meat. I start it, close the lid, set the temp (startup procedure has changed to this according to Traeger service tech) and after 15 or 20 minutes it is not at the set temp yet...in fact it is declining. Well I need to cook on it and cannot wait forever so I open the lid quickly, throw the meat on, and close the lid quickly.
While many people enjoy pellet grills, some find it difficult to use pellets to produce true, flavorful steaks and barbecue since the fuel often lacks the same flavors as traditional grills. That smoky, wood flavor many steaks have is not impossible to get with the right pellet grill however. The Z Grills Wood Pellet Grill sports a combined grill/smoker setup with temperature control for the best pellet grilling experience available.
