Worse yet, they are playing tricks with the perspective. Look at the loading ramp. That's actually the rear gate unmounted and used as a ramp. But see how photographing it from that angle makes it look so much longer.
The entire thing is a deathtrap. A used toyota pickup is better in every regard.
Don't the LLVs that the US postal service uses have flat sides? Similarly for UPS trucks and the containers that eighteen wheelers haul. Seems pretty normal to me.
