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, ...
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.
You like the idea of cooking different types of foods on the grill: If you’re someone who wants to grill food other than meat, the Traeger grilling system gives you this option. With the precise temperature control of the Traeger, cooking things like fruit pies can be a successful endeavor, something you wouldn’t dare try with a propane-fired grill.
I bought this directly from Traeger. Beware that this model is now discontinued. They replaced it with the Traeger Renegade Pro without notice. The new model has an updated saw horse design and a new digital controller with probes. It does not come with the handy spice rack however. To each their own but I'd check with Traeger prior to purchase. That said, I paid more from them so if this is discounted, grab it. I love mine!
Capacity Just like with other grills, cooking capacity is an important consideration. Will you only be using the grill for family dinners, or will you be hosting backyard parties where you’ll need to feed a crowd? While pellet grills cook food quickly, you don’t want to make your guests wait in line while you’re putting the second wave of burgers on the grill.
Traeger's, unlike other models, have a temperature probe, these sensors tell it if the temperature is too low and automatically feeds more pellets to the fire. You can set up the temperature in 5-degree increments. Other brands and cheaper versions only offer three settings low, medium and high. There is no sensor to monitor the temperature. If you are purchasing a pellet grill it is because you can set it and forget it. If you plan to hoover then it makes more sense to use a standard smoker or to transform your grill into a smoker.
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.
