I hear that the 2021 suburban does not have the 31 gallon tank any more and it’s 28 gal and Tahoe down to 24 gal. Can anyone confirm this? Having to Fill up more often with a pack of kids running late to practice.... please GM give us options for large fuel tanks!

That's a little harsh. I take it you've never been to Wyoming. Even along I-80 there aren't that many fuel stops, let alone getting into the interior. Nothing to do in Wyoming? Ever hear of Yellowstone Park, Devils Tower? Course maybe you're a city dweller with a gas station on every corner and fixated on Brokeback Mtn.

This guy gets it!

Yes that is accurate. Both tanks will be getting smaller.

 

2021 Suburban fuel tank 28 gallon vs 2020 was 31 gal

2021 Tahoe fuel tank 24 gallon  vs 2020 was 26 gal
