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, ...

But as said, there are a few things we don’t like; it’s relatively small, doesn’t have a lot cooking space, and the design feels cramped. At the same time, it’s still relatively heavy at 140 lbs.

Or you could just spring for the Traeger Pro 22. There have also been reports of poor quality control, and that the temperature control is very inconsistent, often swinging up and down nearly 30 or 40 degrees.
