I agree, but Devil's Advocate:
The clawing for ever-increasing fuel economy pretty much requires a lot of electronic control on the engine, drivetrain, etc. The drive for more power is demanding it too (see also eTorque). If we were to strip all that out and just make a basic rig with little-to-no computer power (say, what they had in the late 1980s to early 1990s), fuel mileage would drop to 15-18mpg on the six-bangers, and maybe 10-15mpg tops on the Hemis. You'd also lose horsepower (no more VVT), torque (no more full electronic control over the transmission), and more.
If you're willing to live with that, no worries, but electronics is a huge reason why, for instance, that today's little 3.6L V6 Pentastar VVT (305 bhp) can out-perform against the older Ford 4.6L V-8 DOHC (292 bhp)...
Now as for OP? Bring the Crosshair Grille back!
Playing Angel's advocate... (??? LOL)
If we still had the simplicity of the 70's drive train, fuel mileage could easily be managed with some simple tuning (which could come from the factory if they were honestly serous about it)... The only thing that all this computerized CANBUS'd and electronic control crap has done is make a new revenue source for the dealers by making it nearly impossible to maintain or customize your truck. Seriously... A trip to the dealer to reprogram your frickin' computer just so you could add a trailer brake controller or upgrade your stereo?? There is no description for how large of a pile of cacca that is... And not being able to upgrade the lighting to modern LEDs because the computer will think all your lights are burned out?? What the frickin' frick?!
For example... My '78 Bronco had a 460, C6 transmission, part-time transfer case, 8" Rancho lift, and 17x40 Ground Hawg tires... I stripped off all the pollution control crap, added an Edlebrock "Performer Package" (matched cam, intake & carb), upgraded ignition, ****** headers & Cherry Bombs, rebuilt the C6 with a trailer-towing shift package, and re-geared the diffs to get the tires to match the power curve... Very simple and not overly expensive performance upgrades, all but the C6 tranny rebuild were done in my driveway...
I got 15-ish mpg driving around town and 25-ish mpg on the highway (usually running 65-70 mph, screw that 55 nonsense!). Power and torque??? I would put money on the line that I could hook up to most any modern over-computerized vehicle and drag it down the street like a dog on a leash... My new (to me, anyway) 2012 RAM CTD with stock drivetrain??? According to the EVIC I get around 12 in town, 16 has been my best highway mpg. As soon as my new shop is built in my back yard, there's going to be some wrenchin' done to fix that...
Seriously, not meaning to be or sound snarky here, just a comment on some general things said around on different forums regarding modern trucks...
I don't care about fuel mileage or how comfortable the ride may be. If I did, I would have kept my father's Mercedes. I drive a 4x4 truck for the utility and strength of the vehicle. The ride and mileage just go with the vehicle. I want a vehicle that I can pull a loaded equipment trailer at work during the week, put my boat in the water on summertime weekends, and bust through the palmettos and swamps while deer hunting in the fall. That hardly describes what comes out of the auto manufacturers these days...
I may poke fun at the "grocery getters" as I call most trucks today, but honestly, to each their own. If you like what you drive, more power to you, two thumbs up! I just have never owned anything but a 4x4 and simply expect them to be as rough, tough, and brutally honest as I am. The day may come when I can't climb into my RAM, Bronco, or swamp buggy, but you can bet your ass that one way or the other, my mobility scooter will be a 4x4 (even if I have to build one myself!). And it certainly will NOT have a computer to control it!
