> Could there not be a noun, "ass-load"? Absolutely. Had the GGP wrote “shit-ass-load” the whole hyphenated string would be a noun, which is also grammatically correct. But “shit-ass load” is a bit more evocative and digestible than “shit-ass-load”. I would have gone your direction with “assload” (no hyphen) which is a satisfying single noun with no adjective.
