I'm looking to buy a Used Full Size truck and need to know which one would suit me best?

I'm looking to spend around $13K and would like it to be around 100K miles. With that being said I'm around the 2004-2007 models. I'm between the Toyota Tundra, Ford F-150, and a Chevy Silverado. I would like to have a Tacoma but they are out of my price range. I would like to know which truck will run the longest with the least amount of costly repairs. I like the look of the F-150 and Silverado most, but I know that Toyota's run for a long time. Are repair costs for these cars relatively the same?

The F150 is a great choice. They are pretty cheap to fix. They aren't the most amazing on gas but, they get the job done. They are in the price range you want. They last for a long time. There's a range of different trim levels and engines to choose from.
