New Dodge Truck input

Kicking around the idea of upgrading to a new truck. Accountant says I need to spend some money. Who am I to argue

My 06 has 40K on the clock. I like it just fine, but would like more room in the back, so my kids quit kicking the back of the drivers seat. If I upgrade, I will definitely get the megacab.

I've heard of some issues with all the emmissions they placed on the 6.7 and they have problems with sooting up. That is unless you disconnect the EGR.

Anyone have an 07 or newer ? Problems ?
