Yukon XL SLT vs Suburban Z71

You have to make your own decision but they're the same trucks with very subtle package differences

Thanks for taking the time to respond, but what you've offered is no help at all. I need specifics about what makes up the Z71 pkg and whether these things are present in the SLT and what differences there are between the two. Like I said, I seek facts, not vague generalities.

Ok then go to Chevy.com or look under GeneralMotors.com

Maybe late but: The Z-71 off-road package consists of heavy-duty components added to four-wheel drive models for enhanced off-road capability. These trucks came with a limited slip rear differential, that had numerically higher gear ratios. They were equipped with larger off-road tires, and heavy-duty off-road shock absorbers. The suspensions on these trucks were also lifted higher than standard four-wheel drive Silverados.
