Are all super C's 4 wheel drive?

Almost every manufacturer makes a Super C which is really just a C on a Diesel Freightliner or other make chassis. I would think a 4wd Super C is pretty custom and niche. Are you sure the conquest is 4wd? I just looked at a few online and they were not. Maybe some like Nexus or Thor majestic on the Ford F550 might come with the 4wd chassis. Hard to imagine where you'd go in a Super C that you would need 4wd without compromising the limits of the house.
