What's the best truck brand to buy USED?

I'm looking to buy a USED Diesel pickup. What's the best brand to buy? And pros and cons for the top brands: Ford, Chevy, Dodge. I'm looking to get something between 2003-2006 so insights on models in that range are the best!

For Diesels, a GMC (Jimmy) is tops! Chevy would be next!

Ram. Cummins diesel always

Toyota Tacoma

You're looking at 10+ year old vehicles. Forget brand. Look at condition. Anything that's been well looked after will be a better buy than something that's been hammered.

Chevy

F-250, but not '03

Diesel it self.

All three manufacturers make good trucks, the difference is just personal choice. If you are looking for a diesel, I personally like the RAM with the Cummins engine.
