the frame in that area has just the trans crossmember so if its bent it will pull the frame rails around . i bet if you cut that one out the rails would spring back in place . and even if they didnt porta-power it and be done .
i cut down a crew cab frame and made it a srw there easy to play with frames in this area .
and that price point i would already own the truck !
one side note in my state now is there cracking down on ALTERED vehicles ( door sticker ) and they go threw a super crazy inspection process and i have heard there even failing brand new 2018 and 2019 vehicles for violations to the new rules set forth . so i would be a bit leary buying it unless the title shows clean non modified status .
