Ah yes, for all of those thieves looking for a quick buck driving 1300 miles round-trip to Gallup instead of a quick hop down to TJ where they can grab contraband for the return trip. I guess instead of drugs, the New Mexico bandits can bring back some of those cheap (cheep) small-cage eggs back to California, but they’ll have to be fast, like Burt Reynolds did with his eighteen-wheeler.
Here "to unpack" is used in the school literature class sense of "to analyze in detail and discuss". Thus, "a lot to unpack" is a flippant suggestion that a comment could serve as a fruitful subject for discussion (meaning: for unfunny jokes, speculations about the commenter's mental state, socially disapproved activities, and/or political affiliation, etc.)
An "a lot to unpack" comment adds little value by itself. It's basically a verbal reaction emoji.
