That tear drop trailer looks like it is a normal height at the rear.
It is probably just like a normal trailer all the way through from back to front with extra trim and aero pieces in a shell on the outside.
If it does have a bulge in the roof adding more room inside this would help a bit, companies will figure out how to load it...and its been my experience that somebody will always figure out how to cram everything in there so it is impossible to pull anything out without making the stuff stacked next to it fall over.
