Still vibrating at highway speed, disappointed with Suburban

[Big Bopper]

Just a notice if you are looking at one of these 2015 and newer Suburban/Tahoe vehicles. My 2015 Suburban with approx. 21000 miles has vibrated at highway speeds since new. Just like the pickup versions of this chassis. Two new tires, balancing and force grinding has not really ever made it right. I now have two of the tires with very little tread left because of this grinding process to true up the tires. This vehicle has pretty cheap leather seats and a bunch of low class trim. They've really cheapened up a lot of things in these newer versions it appears. I've owned 7 or 8 of the older models through the years in addition to some pickups (all new). This is a really disappointing 60k truck. I turned in a 2012 F150 crew cab when I leased this one and that truck rode better than this one. It also had the ecoboost engine that easily outperforms this 5.3l, especially with a trailer.

My lease will be up in about 6 months so my problem will be gone. Probably will be looking at an Expedition with the Ecoboost. GM's domination of this class of vehicle might end if this is representative of what they offer.
