I bought this 1999 gmc sierra 1500 3 door truck about 4 months ago the body has no sign of rust.but underneath is life threatening I was driving normal speed maybe 55mph and I heard a pop and my frame broke in two different places because of rust. Now I welded it up just to get me back n forth to work. Witch is still life threatening but I have no other choice. I can not afford a new truck especially when I still got 3000 to pay on this one. The frame literally broke in half, under the cab on driver side, and by the back wheel on passenger side. It cause the bed to hit the cab and knock a dent in it. Not safe at all.
