Try Vactor (http://www.vactor.com/). Looks like they're all truck mounted, though. Pretty slick machines.

It's called day lighting , potholing or Hydro Vacing.Most major area's have a company that does this either on their own or as part of an excavation company. I see the utilities around here using them more than backhoes now to open up their underground installed services.One of the bigger companies in North America is called Badger Daylighting. Doing a search on Hydrovac brings up lots of companies. I think that United Rentals also rents small units you can tow behind you but you have to find a place to dump the spoils as all the dirt/mud will not fit back into the hole.

Yes I see United Rentals in the Midwest has towable ones, but none out here in Arizona. The guy at United here hadn't heard of them.
