Mostly on Powerstrokes and Duramax engines... opening the hood shows a complex maze of wires and piping which basically hides the engine... or what we expect to see. But in reality... a couple of hours and you can remove all that clutter out of the way without much fuss at all. Just time. Once your down to the valve covers its all the same.
I'd hardly call opening the hood of an 08 Ram 6. 7L Cummins the same as opening the hood of a 93 W250 6BT. The newer Cummins engines have become nearly as complex... but understandably less cluttered because of # of cylinders and inline configuration.
I'm not advocating a Cummins in a Ford. I've seen plenty of them. I don't own a Ford. This is my opinion and how it should always be: Dodge/Cummins, Ford/IH, GM/Duramax.
As far as looks, I really like the new Dodge HD body. I hate the look of the new Chevy HD. But absolutely love the looks of the new GMC HD grille and (small) headlamps.
I also think the 05-07 Superduty front ends are great, but dislike the new "headlight under" look of the new ones. I DISLIKE monster gigantic headlamp assemblies. Liked 03-05 Ram fronts. Dislike the 06-09 fronts. Just a preference. Its all good.
By the same token... every single time I look at my 91. 5 D250 grille... I do a double take and say "thats a darn good lookin truck". Ram 1st gens are obviously the best looking truck ever created!!!
