Okay are you looking for room the explorer is much bigger inside than the s10 blazer, also the blazer only comes in v6, the explorer comes in 2 v6s and a v8, it also tows about 1500lbs more. There both very good suvs. for the money the explorer has the edge. If you go with the explorer, you want the one with the sohc v6 or the v8, the other v6 sucks. If you want more info email me, and I can get you a great price on 1 also
