My Silverado crew cab is 10 years old, and it's been totally reliable. I'm about to upgrade its head unit, and that takes some significant shenanigans under the dash. Still, it's a user-maintained truck.
While I'm a little concerned with the price of new trucks, I'm more concerned with their long term maintainability. If I bought a new truck, I could change the oil and maybe even replace the battery myself. But everything else is so electronically integrated that any change or glitch in it would mean a trip to the dealer, and -- after the warranty is gone -- a simply ridiculous bill.
I think I need a truck like the old Power Wagons, where I can hose off the mud, then open the door and hose off the floor. Not much in the way of creature comforts, but zero trips to the dealer. It'd be even better if it were Diesel powered.
