Lol.... I take it you still use a "flip" cell phone, regular old rotary thermo stat controller for the house, and an am/fm radio in your vehicle(s). Technology moves right along friend. Touch screen units are the standard for controlling all audio functions and even climate control in some vehicles. It's fast, simple, and safer. Not to mention much more user friendly. If you're sportin' a smart phone, you should "get it." Not to mention, it's what 95%+ of the consumer base wants.
Might as well just go diesel.... I know you like big blocks, but again.... that whole "technology" thing... Today's small block can put a woopin' on yesterday's big block towing. As I said, we will never see a big block gas engine again. 95%+ of the consumer base does NOT want it and buying trends show people wanting gas will stick with a small block and the people needing that torque to move weight just go strait to diesel. It's why the 8.1L went bye bye in the first place.
Mmmmm... touch screens, leather seats, and a butt cooler that is built in. Paradise on wheels.... The manufacturers make all that stuff, because it's what 95%+ of the consumer base wants, and is willing to get their check book out for. Not even everyone on the "4x4" sites even agree with you. Lots of guys use old trucks and like that, and many buy newer stuff with those features too. The few that make up your crowd of thought on what a manu should build is not even worth it for the manufacturer to draw up.
But seriously, I have a buddy that last year bought a brand new 2015 Dodge cummins 2500 4x4 6spd. It's just like you like for the most part. Cloth seats, rubber mat flooring, no frills for about $40K IIRC. Thats cheap for a brand new truck. That is basically what I want when I get two 4th gen 4500 Dodges soon to replace my Fords. They are perfect for my work needs, cloth seats, rubber floors, but still have power windows/locks and a simple touch screen to manage my calls/audio.
I personally don't make payments like that. I buy 2-3 years old usually and either just pay cash or finance some of it to keep me under $400 a month. I mean really, everything is expensive today. Houses, cars, food, you name it. It's no surprise what stuff goes for and every year inflation drives everything up.
Even if you could get GM to "reissue" your dream truck and kick out a brand spankin' new 80's K30 3+3 with that 8.1L, you'd still be looking at a $35K price tag for that truck, almost guaranteed.
