Of the problems I've had with vehicles, power windows and door locks rate at the bottom of the list. PDL, when they "fail" it's usually just back to the manual level, so no loss there.
My Silverado, 1999, is at 215k with the original window motors. No problem and they are still very strong. I'm not too worried about them...when they eventually do fail, it'll be $100 per door to replace. Not that big of a deal. I do like the abililty to roll down and roll up my windows quickly and without having to reach all the way to the other side of the truck to crank down the opposite window. Now, back when I had a blazer, yeah the power windows failed a lot more often but I think that was due to an undersized motor. Weren't hard at all to replace, either, on that model.
Mine also has carpet. And it hasn't been a problem. I just vacuum the dirt out a couple times a year. Its still in great shape. Big whoop. And yes, before you ask, I am an outdoors person so I've always got mud on my boots and filthy gear.
Other than price, here are the biggest issues with modern gasoline powered trucks...transmissions (putting a car transmission in a fullsize pickup truck is *expletive deleted* retarded...thanks GM) and the extreme electronics that are used in modern vehicles for engine and vehicle management. Diesels...the whole *expletive deleted*ing engine is *expletive deleted*it.
Oh, IIRC, Dodge is coming out with a diesel V6 for their half ton sometime soon. It will be the EPA-mandated sucky new diesel, though. The one with awful MPG and the asinine soot trap dealie-o.
*expletive deleted*ing EPA...
