Check out the Pellet Grill forum. I asked a similar question a few days ago.

I did email
Camp Chef and got the following response.

Thank you for your email, yes the ZG is the model grill we manufacture for
Dick's Sporting Goods. The ZG is just like our PG24SG
https://www.campchef.com/pg24sg.html, it will have the slide and grill
technology. if you let me know what specs you would like to know I can see if I
can find that information for you. Let us know if you have any other questions,
have a great day.

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, ...
It appears to me to be a DLX with the direct heat feature, upgraded legs, a larger upper grill shelf, and upgraded controller with dual meat probes.
