Difference between flat and profiled body panels?

The Arctic Fox trailer I'm looking at online seems to have all, or mainly flat panels. Doing a search for Arctic Fox opinions on this site brings up a lot of positive reviews on the build quality. I get the impression that it's a combination of what's seen on the surface with what's going on beneath.
