Hey everyone. new here! That being said, I've been looking very close at the '99-'02 silverados, as I would like to purchase one. Or rather trade my '00 blazer 4wd for one lol. I was hoping someone could help me out, I've never owned one before and I would like to know more about them! As far as what I would like to find, 2wd or 4wd doesn't really matter. Im looking at extended cabs. My main concern is if I will get the same mpg or better than I get now, in my blazer (14 city up to 19 hwy). I heard the 4.8 does a little better than that, but the 5.3 does around the same. Can anyone confirm this? (I know what you're thinking, get a car if you are that concerned about mpg. But I need a full sized truck for hauling quads and snowmobiles) Also, all of the silverados in that price range have over 150,000 miles(which I am ok with), is there any common issues I should check for with that many miles? Thanks in advance everyone!
