I just purchased a 2006 Dodge Ram 1500 Thunderroad. It is my first full size truck. I had a 2002 Neon that I loved so I decided to stay with dodge. It has the "Smart Hemi" engine and 35000 miles. It is Patriot blue. I paid $14,500. The body is perfect and was sold as a "Brand Spankin Used" certified truck. It is fully loaded except it dosent have leather seats. Did I buy a good truck and what should I know about them as a new truck owner? Are there any commen problems with this model that I should look out for? Will Dodge give me a hard time with the warentee if I alter it in any way or am I better off keeping it as stock as possible? Any advice would be appreciated.
