Oh for sure, if he had a raised cap on his truck taller than his cab, there would be far less “exposure” of the frontal area of his trailer.
The Jeep Grand Cherokee SRT is far from an ideal shape for aero by itself, but it doesn’t seems too bad overall if paired with a trailer that essentially matches it’s cross section with blended curves, and presumably a more efficient tail end of the trailer compared to the larger tail end of the Jeep.
