2500 I would think so too but not necessarily. I'm surprised but then again mine didn't come with a power steering cooler but yet I have everything else accept the rear hitch lol. I think I may have found the misfire cause....You may have partially answered the question on my crew cab. I was going to replace cap/rotor and plugs; will be ordering them Monday once my paycheck comes in. Also I noticed that this truck doesn't seem to have an external transmission cooler, though it does have the oil cooler and power steering cooler. I would have thought a truck like that (1 ton crew cab) would've had a trans cooler?
