The market for Spanish words is very slow, camiones or trucks is not something people in Latin America countries (to which the domain would target) looks for on the Internet, here buyers generally go to places known by mechanics, taxi drivers and people who are already purchased a camion.
I do not see a future to this domain, perhaps camion.com or camiones.com would have been a whole different story. But as someone already said it has other good points, it is short and memorable, but finding an end user will be very tough to say the least.
