Long story short, I lifted the vehicle using the rear jacking points and thought it would be reasonable to use the frame rails for the jack stands in the rear as they are the jack point in the front... wrong. Turns out the forward "2" frame rail area is reinforced. I now have some minor dents in each side rear frame rail where the stands were, but more on the passenger side. The passenger-side dent slightly affects the "wall" of the frame rail wall and not just the flat top or corner of the top of the frame rail.
I did this due to the lack of room in the rear concerning floor jack and jack stand space. I know some folks use the lower control arm where it mounts to the subframe for jacking but i digress. My new approach is to diagonally position the floor jack and lift the rear "2" location then use jack stands with rubber adapters on the pinch welds to prevent bending. Just enough room.
Is such slight frame rail damage as I have acquired detrimental to the safety or value of the vehicle? I can post pictures but I'm comfortable calling the damage minor.
