Concerning rust? (8 Viewers)

[Needleses]

Hey y’all, wondering if I need to be concerned by this rust on an FJ62? Just surface stuff? Or should I be worried about taking this overlanding?

Cheers & thanks for any advice!

Take a scraping device such as a big screwdriver to it in order to test if it's just surface or goes deeper. Also could pound on the frame with a hammer. Photo #2 looks the worst to me. Mostly looks like surface IMO.
