Hi everybody this is my first post. I will be buying either a 7.3 or 6.0 before weeks end so I will be spending a lot of time on these forums soon. I found what I think to be a steal but want the feedback from the community. A mechanically sound truck, 188k miles, 4x4, no oil leaks and body is in good shape. It’s an estate sale so it’s only listed at $4k but the frame has some rust issues. Mostly the rails that go side to side under the bed. My budget was about $8k so I will have $4k+ for repairs.. should I buy? Thanks!
