Mid-sized cars show an average death rate of 60 according to your link, the RAM 1500 Classic (previous body style) is 23. Silverado is even lower at 14.It is interesting that this isn't always true.

The average deathrate for newer 1/2 ton pickups is only a bit better than average of all vehicles?
There are a few midsize and small cars and wagons that are have a much lower deathrate than 1/2 tons, so I guess it shows that in spite of their inherent disadvantages, design and their average driver habits makes more of a difference than mass?
I think what's more interesting is the range. The worst full-sized Pick-up has a death rate of 51 and mid-sized SUV's it's 62, while for mid-sized cars, it's 113.
You are ~7x more likely to die in a KIA Optima (80) than a WK2 Grand Cherokee (12) according to this list.
Though the fact that it stops at 2020, and the tiny sample sizes for some of these vehicles, I think limits the ability to draw those sorts of conclusions honestly and likely is the reason we get really weird variations in the data, like the 2WD Traverse having a death rate of 30, while the 4WD version has a death rate of 6. Or the Nissan Pathfinder 2WD having a death rate of 0, while the 4WD version is 25.
