Overall, not bad at all and shouldn't give you any issues (even AHC lines) in its current condition if you treat it/fluid film. If it's ever seen salt in the winter things up front like tow hooks/control arms would be the first to show it.
Looking at your first pic, the transfer case cover looks really new and may have been replaced/painted as that gets rusty first. Looking at your last pic, it's possible that the front skids/tow hooks have been replaced when I see the bolts on your suspension.
There is much worse out there. Obviously this is not a Southwest vehicle its whole life but not many are.
