6.7 or 5.9?

Dodge has become our truck of choice since we made the decision to tow a 14k trailer. Question is, which setup? I like the idea of the auto 6 speed and the exhaust brake but am concerned about engine problems with the 6.7 Ideally, cost wise I would like to buy a 2006 5.9, quad cab dually 4x4 long bed to tow with. Should I be concerned with the reliability of the 4 speed auto available that year?
Can I put an exhaust brake on a 5.9, 4 speed auto without affecting any warrantys(Dodge or extended)?
Rear axle ratio: 3.73 or 4.10?
I would like to "do it right the first time" and get the correct setup. Any advice/recommendations would be appreciated.
