2015 Dodge 2500 6.7L diesel 6spd Auto 8ft bed

I have a 2014 4x4 short box (live in the city and it is my daily driver too) with almost 14K miles. Heavy traffic it gets about 14.5 to 15.5, empty highway 20 if I keep it under 70, and loaded with the trailer 9.5 to 13. Speed makes a huge difference with the trailer, if I can stay on the smaller roads in the 62 to 65 range it will get 13, but bump it up to 75 and it goes to hell. The truck is comfortable, nothing has gone wrong, and we are happy with it. Only thing I would do different would be to buy a megacab next time for the inside storage space. If the infotainment system is important to you, Ram has the others beaten by a mile. Ford's is Microsoft that they are replacing next year because of complaints and warranty claims, GM's feels crude and designed by a six year old, and Ram's is very nice. I have done a lot of UI design in the past, and Ram nailed this one.
