Vortex generators may reduce drag and clean up the air passing over the spoiler, but you are literally creating a huge sucking vortex behind the truck. The only way to address that is to direct moving air downwards across the back of the truck effectively disrupting that low pressure area.
Removing the spoiler will have zero effect, you literally need some sort of air scoop sticking up into the flow coming off the back of the roof and directing air straight down breaking up that vortex.
The 4th gen was the same way. Rear window was rolled down and back up for effect:
