For those that know the difference, what - if any changes to the Z21 for 2018/2019? Most curious about driver console and trailer fenders. I just left a BPS and climbed in one and I didn't comfortably fit at driver console. My left knee didn't fit under the bottom of dash. I'm 6'3". I thought for sure the last one I sat in was huge under there, but the dash looks like it came down farther than what I remember. The fiberglass trailer fenders looked a lot thinner too and I struggled finding a stepping spot climbing out. Didn't remember that either. Might be in the market in the next couple of weeks and love the layout. These are deal breakers for me, but I was looking at 2017's and was hoping these 2 things were recent changes by Nitro.
