Brian,
Have you driven the Ram yet? About 2 months ago I was thinking about doing the same thing but my reason was for the extra horsepower. I went to the dealer and test drove a hemi quad cab and it gave a nice ride and the power was excellent. I wasn't impressed with the interior though. It seemed cheap and dull. The back also had less legroom and it was not very comfortable. Also, they come pretty base and by the time I added running boards, sunroof, etc the price increased considerably. They just redesigned the ram and it is supposed to have many many upgrades both with the engine, and the interior. If I were you I would wait for the 06 to come our first. It is supposed to get much better gas mileage because it shuts down the extra cylinders when they are not needed. I am waiting until the 07 Trac comes out before I go looking at anything again. If it is like the concept and the price is right that's what I would like to get.
