No trail boss here but I used to have the GMC version (the Canyon). I'm 5'11" and had plenty of adjustment left over...but I'd definitely see how you feel in one first.
I had the 3.6, solid engine, easy to do preventative maintenance on, tech was modern and not glitchy. My understanding is the newer ones have the 8 speed auto now. Drove nice, but the biggest thing I appreciated was the quietness of the interior on the highway - my wife's RAV seems absurdly loud in comparison.
I'd be driving it today but started doing nearly 100/mi a day in commuting, so turbo diesel it was.
