Trucks are MADE to rust out now. They want you to buy a new one every five years.
As a matter of fact, Ford is coming out with an aluminum truck this fall. Hopefully it will last for a long time. (I still have a 66 Chevy Truck that is still going.)
I will be interested to see how that goes...
However, I have my doubts. The auto industry has had the capability of creating body panels with alloys for a LONG time that are more resistant to rust, and in many cases the metal itself is stronger.
Why aluminum? it has no memory and breaks/cracks easy. Why not alumanized steel or one of the many stainless alloys? Any one of them would last ten times as long as the mild steel they are using now.
The answer is pretty simple. Give me a good truck with few electronics to break and body panels that wont rot away in four or five years and I will own that truck the rest of my life.. they don't want me to own a truck the rest of my life. They want me to buy a new one every four or five years.
My 89 is 25 years old. It still runs great. Yep, I have had to fix it. put another trans in it, brakes etc etc... but those are all things I can do myself, and did do myself. I have less than 10,000 invested in the truck right now, counting new tires, transmission, brakes, everything I have had to do to it.. a new truck every five years, with 600 dollar a month payments would have cost me $180,000.00 dollars after making those payments for 25 years in a row. So, as I see it. I can buy another engine, trans is already done, have the transfer case, front end and rear diff rebuilt. Have it repainted, and still be $170,000.00 ahead of the game. My truck still runs the stock fuel injection, and it gets as good or BETTER fuel economy than the brand new ones.
My wife didn't figure this out until she FORCED me to go look at new trucks... that new extended cab Duramax 3/4 ton with Alison trans was $60,000.00 from the lot... She hasnt complained one bit about my old truck since then.
