There was a thread on the Dope a long time ago that implied strongly that anyone selling “ice cream” from a truck in the 70s was using it as a cover for dealing weed. I’ll see if I can find it
This the guy?

This bastard springs to mind
My ex-husband and I used to drive separate ice cream trucks. I’d never heard of a stereotype that drivers were considered creepsters, but it has been decades. I had fun doing it, but the pay was shitty, and we had to make an 80-mile round-trip each day to pick up ice cream. We only did it for a few months.
I knew that it was based on a real conflict but it was fun to read the Wikipedia page.
Here’s a clip from the movie where Dickie Bird witnesses the first salvo in the war. (Another clip: “Meeting Mr. Bunny”)
“Hello folks!”
Correction: The first clip is “Meeting Mr. Bunny” and the 2nd clip is “A Visit to Mr. Bunny.”
Since I’ll never again have an excuse to post this, here’s a song I love.
Mary Coughlan - “Ice Cream Man”
I think part of it is they come around here in the dead of winter when it’s lashing rain or snowing. Who the fuck is getting ice cream when the weather’s like that?
People who are interested in buying the secondary products mentioned above? You might say that Mr. “Jones” is “tweaking” in the rain to just get some of that “ice” cream, with such wonderful flavors like… “heroin.”
I don’t think it’s any more complicated than “men in vans enticing kids with sweets are creepy”. O, our lost innocence.
I don’t know, but it makes me sad. I adored our local ice cream truck guy when I was a kid (under age 15). We would chat, he would give me rides home from school (not in the truck, but with me sitting on the bumper outside the back), and the occasional freebie. Never did or said anything suspect, though now all of what he did do would be suspect. 
This incident happened recently near where I live.
Am I a bad person if my first thought is not “oh how horrible,” but “huh. He sells ice cream. His name is Sellers. Must remember that for one of those ‘name matches the job’ threads.”
And umm, “oral sex barriers.” Being safe? I don’t think I’ve seen one of those or even a place selling them in real life. And yes, I’ve read a sex catalog.
