Ram 2500 - which towing features are best/good/unnecessary?

I randomly looked at the 2016 brochure last night and found that tradesman had rear-only park sensors, but we want both. So tradesman is out. I could not find anything on my must or desirable list that the outdoorsman ruled out, so I guess outdoorsman is still in the running!

Going to head back to the dealership today (hopefully, busy week) and look at some door jams on both 2500's and 3500's ...
