Objectively I think it just comes down to cost vs what you get. This is the equation that I was considering when I was shopping for my truck. At the time, the new (refresh) RSTs were being discounted but TBs were not only not discounted, but really hard to even find. So my plan was to just lift an RST. I figured i'd be changing out the wheels and tires regardless of trim anyway, so spending $500-600 for a lift was no problem. The problem for me was that it wasn't possible to get really any of the options I wanted on a refresh truck...GM wasn't building them. That fact combined with all the limitations of the refresh trucks pushed me into shopping the "barely used" market and there I found that I could get all the options I wanted, without all the limitations, and a Trail Boss ended up being by far the more cost effective option. Not to mention I saved almost $20g's.
