The CXT comes with a monster DT 466 diesel engine. It can tow 20 tons (that's 40,000 pounds), but it was built with interior comfort in mind just as much as performance. The air ride suspension system gives the occupants a soft feel even over rocky terrain. There are also individual bucket seats for each passenger. You won't feel like you're in a huge truck when you're in a CXT.
Some of the other luxury options include leather seats, satellite radio, and DVD entertainment system for when the satellite radio gets boring, like when Dr. Laura is on or something.
These trucks are obviously very expensive. They retail for $115,000, which is actually quite reasonable when you consider what it's packing. That price does not include the wrath you'll get from environmentalists.
You'll have trouble getting one of these, as most are sold out and tend to go to high profile buyers like Ashton Kutcher, who you know doesn't appreciate as much as you or I would. You might find one listed on eBay on occasion, but I won't make any promises.
