¹ With the Heavy-Duty Trailering Package (NHT): the maker’s figure for the configuration with that factory option.

A dash means the maker’s documents we have don’t give that number for that configuration, and a column with no number for any configuration of the year isn’t shown. “Door label” means the maker prints it only on each vehicle’s certification label, and “not published” that the maker doesn’t print it, or points elsewhere. “Up to” is a ceiling the maker prints over several configurations; a range is the maker’s own, printed across the grades of that configuration.

02 / What changed

New for 2020

The 2020 Yukon against the 2019, the previous model year we hold. Only what GMC’s documents show: nothing here is inferred.

No retail configuration added or dropped: the 8 sold in the 2019 are all here.
Towing: 6,000–8,500 lb (2019: 8,400–8,500 lb).
Same range as the 2019: curb weight and length.

The 2020 documents

2 documents behind the 2020 Yukon’s figures. The maker’s own come first; a third-party page fills in only a number the maker doesn’t publish, and wears its own mark.

Documents last checked Oct 12, 2026. How we read them and what the marks mean: how we source the numbers. A figure doesn’t match its document? Report a wrong number.
