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, ...
You want longevity in a pellet grill: As the Traeger brand name has been around for a few decades, you can have some peace of mind that you’re purchasing a grill that should have replacement parts available for the foreseeable future. And Traeger grills tend to have good longevity ratings, working in top condition for several years, as long as you follow the manufacturer’s maintenance recommendations.
I had heard about Traeger from a friend who was at a conference where the catering was done on one of the commercial units. He had said the food the it made was mind blowing, and on a late night impulse buy I decided to purchase this from Amazon - as an open box/scratch and dent for about $800.There are some less expensive grills available, I have never owned them so I can't comment on them. i started to get a little buyers remorse with all the negative reviews this grill had received, but decided to give it a fair shot. It arrived quickly not by UPS but from trucking company. Despite being listed as damaged box/open box it was well packaged no damage. Assembly took 30 min by just me, assembly tools were included. Stood it up off the floor and filled the hopper with mesquite and followed break in procedure listed to cook off any manufacturing oil etc. Let it cool retired it once more to make sure it was seasoned let it cool again and was ready to go. I purchased an IGrill wireless thermometer to go with it which I would recommend also. I signed up to the Traeger recipe sight and they send a recipe every few days, and you can browse the website for some inspiration. Since I have owned this I have gone thru about 3 bags of pellets including alder mesquite and hickory. I have grilled Trout ( the smoked trout dip list on the website was amazing) as well as trout fillets, Salmon, Haddock, Ribs, Brisket, Pulled Pork x 3 and 2 prime ribs and 2 loafs of bread Jerkey ( smoking now) butternut squash etc etc . All the food I can only say is mind-blowing - enough so that 4 of my friends have purchased the smaller Traeger's for themselves. It has all been incredibly easy - just season, set the temp put the food on and the temp probes in and forget it- the wireless I grill continually upgrades my phone so I can keep working inside and not have to worry. It has never failed to light, caught on fire, overheated or preformed to anything other perfection for me. I can't speak for all the other negative reviews but I have had nothing but success with this, the Weber propane I own hasn't been touched is just taking up space it can't compare to this thing. Its a big purchase at close to 1k but is incredibly versatile I can't speak about customer service response because I haven't needed them, but if you are concerned I would call the headquarters and see how hard it is to get someone on the phone. The Temp probe is off by a few degrees compared to my Igrill reading but the grill has no trouble maintaining a narrow temp window if you keep the lid closed and don't F%$k with it . Most important it has bought back some passion to cooking, and made me want to try new things which is priceless.
Portability Even if you never take your pellet grill on a road trip, you might want to move it from one side of the yard to the other when you’re having a party, or move it out of the way when you’re not using it. While some pellet grills are light enough to pick up and carry, wheels make the job easier. Of course, if you have a permanent spot for your grill, portability is less of a consideration.
Although these are marketed as grills, they do much more, including baking or roasting. Because they heat by convection, you might not get the grill marks that a gas or charcoal grill will give you, but you also won’t have the flame-up problems. While many pellet grills offer high cooking temperatures, the maximum depends on ambient temperature and wind. Many users wrap their grills in special insulating covers to help maintain heat, reduce fuel use, and reach the higher temperatures they desire.
