I suggest that all the people here suggesting the name is worth mid $xxx put up and shut up and make an offer of LOW $xxx.
That said Commercials is a much better UK term and I wouldn't expect people in the US to realize that.
Mid XXX to low X,XXX end user. Focus on UK companies in the Haulage industry, imho. Plenty of horrible domains out there search google for site:*Commercials.co.uk to see what I mean.. hyphens galore

I disagree "Commercial" is a much better UK term with over 22,000 monthly Local exacts compared to 880 for "Commercials". Commercial properties and commercial Insurance are Big businesses here. Again, selling a .co to a UK company does not make sense and will be difficult as the TLD is not relevant to the UK.
But I wish you good luck.
