I'd vote Tacoma also - you'd have to go clear back to a square body S10 before they were any good (And a V8 fits nice in them...) Colorado's suck - maybe the newest ones are OK but the older ones were junk. High mileage 4.0L Fords need the timing chains replaced and that involves removing the motor. Ford in the wisdom decided that they would put timing chains on both ends of the motor (I know of one that has over 400K miles and is still going strong but with loose chains). Older V6 yota's have had problems with their heads. Toyota 4 cylinder manual's are the bullet proof answer.
One that wasn't mentioned was a Nissan - the 3l V6 was a good motor, but the rest of the truck is questionable. Nissans can be had thousands cheaper than Toyota's of the same vintage. Honda Ridgline?? They have a pretty bulletproof drivetrain, although it's hard to call them a truck, I'm not sure that I'd haul dirt or rock in the back but I'd pull a small boat or trailer with them. I've got two J series Honda V6's in the driveway right now and I've had good luck with both of them.
