I wrote out a 45 minuet reply to this as to all the pros and cons we have had with out 16xrb, and when i hit post it logged me out and lost it all....
We bought a 2016 16xrb last year and used it extensively and i would highly recommend one to anyone that asks. We are a family of 4, and have no space issues whatsoever. Also i am towing it with a 1999 jeep grand cherokee v8 and with about 4000 miles towed last summer i have a pretty good handle on what works.
As for towing, check this guide for your specific truck. Its not as exact as running your vin number, but should give you a good idea
