Sounds like you've made up your mind, which is great and was the intention of your thread. I will however leave you with this as I consider myself to be a "common sense" person as well. I am on my 10th truck (3rd Ram - not sequentially), I've owned an 8k lb. travel trailer, I've traded a truck in for it's lack of towing ability. My truck is configured the way it is based off of my personal experience. If my prior experience were travelling 20-30 miles on the highway to the office the last 25 years, no towing, no bigger tires, I'd have 3.21s all day long. I only contribute to your thread because I have experience that if you have a similar life path with family, camping and towing, my experience could help.
I don't know if you and your family camp now but if you do, talk with other campers who tow trailers and find out opinion on it. Vehicle discussion and configuration and a few beers has been a great way to meet people and have a good time.
