Thanks to Warpo, I now know these post-apocalyptic-themed, Mad Max-inspired toys exist. Billed by Tonka as a “male-action survival” line for “older boys” and following the release of Mad Max: Beyond Thunderdome (1985), it was a good shot, if a misfire (profit-wise), by Tonka. The post-nuke trope was in high gear in film, comics, and especially neo-pulp novels at the time, but I would say the concept appealed mostly to boys older than the 5-10 age range Tonka was targeting.
