I'm a newbie and looking to buy a used Silverado or Sierra. I have no idea where to start for I only know Ford F150s. I said it and it's out there. I'm looking to jump ships. I have $10k limit, looking for 4x4, above 4.6 liter with a V8. I don't know anything about years on what were the best from late models to current models. Can anyone place me in the right direction so I know what to look for with the cap I have and the criteria I'm looking to meet. Thank you so much.
