I personally only have 5,000 miles on my 2015 Trail. My former employer bought 4 of them in late 2009 when the 2010s were just coming out. Currently the highest mileage one has just over 190,000. They went to Toyota's with the intent that they would outlast the old Trailblazers that they were getting and to replace that model since it was discontinued.
I was hoping to purchase it at around 250,000 miles when it gets retired but I changed company's a few months ago. They were all SR5 models with occasional off road use. No issues, the only maintenance has been oil changes and all fluids replaced at 100k.
