Whoever designed that add had to be off his rocker. It should be no surprise that Beavis's creator was inspired by this dealer:
I had that 3-piece Tonka set, but my set had the dump truck, cement mixer and pickup. The dump truck was orange, the mixer was red with a white drum and the pickup was sky blue, the same sky blue on the Jeepster.
Showing my age........ I was 'done' as a kid with my Tonka Trucks, even before the Mini-Tonkas and Mighty Tonkas ever came out. All of mine were the middle, 'original size'. The front ends resembled '56 Fords or '59/'60 Fords.
There's a pic my dad took of my two oldest brothers, who are holding identical Tonka/Buddy-L/Structo, you name it, trucks from that early Sixties period.
