I have owned my 2006 Dodge Ram 2500 SLT 4WD QUAD CAB 5.7L now about 20 months and I do not have a single complaint. It is extremely reliable and fun to drive and pretty much rides like a refined truck. I get over 15 mpg driving it easy to and from work and around town and if I drive it hard the mileage drops to around 13.5 mpg. Handling and braking are excellent as is the interior functionality and comfort with plenty of storage space under the rear seat.
