Watching Mad Max (1979).
More a station wagon than a van, but it’s called a ‘panel van’. Check out the prices of Holden Sandman ‘panel vans’.
The first this this thread made me think of what Cheech and Chong’s lowrider van.
“Ayyy, pendeckos!” snerk
If C.W. (“Convoy”) McCall and a groovy hippie chick had sex in a room full of Frank Frazetta posters, their love child would have been the 1970s custom van culture. 
Ahem.
The first thing this thread made me think of was Cheech and Chong’s lowrider van.
I am never posting from my phone again. ::sigh::
Cheech and Chong’s other van: cheech and chong fiberweed van - Bing
I didn’t have a Shaggin’ Wagon, but my first car (really it was my dad’s car, but I’m the only one who ever drove it) was a 1977 Ford Pinto Cruising Wagon, silver with racing stripes, a fishbowl window in the back, red shag carpeting and a fake rubber spoiler under the front bumper. She was the Sara Lee (as opposed to the General Lee).
Thisis the closest I could find online, except, you know, silver.
This thread is making me want to take our 2005 Dodge Caravan dogmobile and trick it out. 
Too bad it’s such a POS mechanically.
If this van’s a rockin, don’t bother knockin.
Kelso: If this van’s a-rockin’… we’re in there doing it.
You misspelled AWESOME
You misspelled FAR OUT!
Why settle for The Van when you could go for Super Van (formerly, The Love Machine)?
Those are decorated trucks. Japanese custom vans look like this. Totally separate sub-culture and completely different aesthetics.
The only thing that ever made my Mother forbid me to date someone, was a guy whose Dad had given him his old custom van with a dragon mural on the side. She was having NONE of either the van or the morals she assumed he had also inherited. ROFL
She was probably right about that one, too.
Even AMC and International Harvester attempted to make vans.

This is in the first link in the the OP.
I would totally drive one
My parents really wanted one of those. Finally in 1980 they got a Ford Econoline cargo van, and had it customized with captains chairs, table, CB radio, bench/bed, the whole setup. No crazy mural, just silver with blue and silver stripes. I drove it off and on through high school and college. My Dad finally sold it around 2000 to a band, because he was living in Austin.
Which looks nothing like the car I drove - hence the pic i posted. But thanks for the heads-up.
