Ok, well that's sort of a lie. I mean, he did stuff. But nothing to distinguish himself from all the other Throttlebots. He just rolled with them, said little, did little. He got turned into a toy car. He evaded capture by the Decepticons. He was placed in his reconstructed Throttlebot body, only to be totalled by Starscream soon after. In the cartoons, he appeared briefly in the Rebirth. Then in the IDWverse, he was shot whilst trying to shoot Sixshot. That's it.
His Tech Spec bio doesn't help. It's a bit vague, if I'm being honest. If all it gives you is 'is a bit vain and can pull heavy stuff', then you're going to have to work hard to get any fiction of worth out there. Especially in a period when all Hasbro wanted to do is get the toys out there and be seen.
Wide Load suffers from cheap Transformer disease; because the Throttlebots weren't the most expensive toys, there was little impetus to try and build any kind of fiction around them, because they weren't the toys that Hasbro really wanted your mum and dad to buy. That was the Powermaster Prime, or Galvatron, or Ultra Magnus. So they got all the cool stories, and the Throttlebots were turned into r/c cars. Boo.
