I’m average height 6’ and not really a seat connessuer, if it’s not lumpy and the springs ain’t broke it’s generally good enough for me.
But having had a few new GMs in the last several years, their truck seats (cloth and leather but same size and shape) have abnormally short seat bottoms, in my opinion.
For a long trip, I’d take the 90k mile cloth seat on top of a rough suspension in the brodozer over the leather seat in my new Silverado 1/2 ton.
Personally I’d buy a GM truck no problem, seats aside, but the GM truck seat bottoms are definitely less comfortable than any Ford or Dodge truck I’ve had over the last 20? Years. Caveat I have not been in any 2017-up super duty’s or 2015-up F150s.
