I emailed the lady at the development office to see if she could help. While our neighborhood is still under construction the HOA is just run by some company - there are no meetings and no resident officers or anything like that.
I also emailed the trucking company - maybe I will get further with an email than a phone call. Plus now its a weekday so the bosses will probably get the info whereas on the weekend it probably wasnt the people in charge that we talked to.
I also tried calling the city but I got nowhere with them. The neighbor next door is a lawyer so I guess I will just leave it up to him to deal with it. I think they did say something early on to the builder but they probably wrongly assumed - like we did - that once people lived there it would stop. If we do see the truck moved we all talked about parking our cars where he has been parking

. But we cant do that all the time. I also thought about figuring out where he lives (we know what his SUV looks like so we can find his house easily) and parking in front of his house. But that would just stir up more ugliness.
