Finally, Long Haul, the dumptruck/earth mover. TFWiki says he is a Hitachi DH321, which I couldn't find many photos of, but again, what I did find is very similar. He's a bit boxier here and here, but I won't body shame.

Scavenger is an excavator, based on a Komatsu PC200-1 or similar model, and again, this is pretty accurate. The configuration of the cab seems to vary a bit, but that's about it.

Bonecrusher, the bulldozer, is apparently a Caterpillar D9G. Like Scrapper's basis, this seems to come in a few configurations, and he's definitely a more stylized version of his basis. Honestly, a LOT of bulldozers could be his basis.

Hook, the crane, is the only one who is slightly larger than the others, but not by an appreciable amount. TFWiki identifies him as a Nissan Diesel Unic K-160B, and yeah, this is pretty spot on.

Out of all of them, he is probably the one who most closely resembles his real world counterpart.

Next up, Mixmaster, a cement mixer and chemist.
TFWiki says he is based on either a Volvo F12 or Nissan diesel truck. And in this case, I can see elements of him in both examples, though neither is exact. His front end sits unrealistically low for a vehicle like this.

Now for the team itself.
First up, Scrapper!
A front loader who, according to TFWiki, is vaguely based on a Caterpillar CAT 966C.
This vehicle seems to come in a few variations, and I can mostly see it, I think.

Trivia: Scrapper's original name was going to be "Gravedigger".
