I had a 2026 TB for one week, and now have a 25 z71. It was nice and looked great on the outside, but inside was horrible even with the evotech seats and wrapped steering wheel. Everything is hard plastic, there is no telescoping steering wheel option, the sun visors do not extend and you tend to hear more exterior noise. The headlights are very yellow and dim, I guess you can put LED bulbs in, but it'll still never have as good of a focused light output as stock led housings.
What I did like was it had the tech, camera and radar cruise control. Which my z71 does not have sadly. Other than that, the z71 has a much nicer interior and factory LED headlights which make a huge difference. The TB has a lot of potential but it is ruined by the terrible interior and crap headlights on a 46k truck. Very sad GM would release something so basic and expensive.
