i believe they are registered as commercial trucks considering it's essentially a dump truck...and i assume you need a cdl to drive it....i dunno...i passed a red CXT last week on i20 and they are sick trucks.....the shop next to our warehouse builds custom boxes and beds for f550's, f650's, kodiak 4500's internationals all kinds of stuff....i go and sneak into the cabs....they sit like 2 feet off the ground stock....awesome trucks....
