I have a 2000 blazer and was wanting to know what the max weight I could tow with it

 

I don't know the exact weight, but mine flat towed my dead cobalt (~2800 lbs) about 20 miles just fine!

Other than that, a 2,000 lb trailer a few times. Dropped the back end a few inches from my wore out leafs, but no other problems.

edit: according to edmunds, it's 5500 lbs.

 

My owners manual on my '96 says 4500lbs if equiped with the transmission cooler and a proper hitch.
