It comes down to if you want a truck built out of high strength rolled steel or aluminum.
What is built out of high strength rolled steel? Hulls of Submarines.
What is built out of aluminum? Beer cans.

With respect you might want to be careful what you believe from commercials. I've seen that GM Commercial and laughed.
"Rolled" steel comes in two basic types HRS and CRS Hot Rolled and Cold rolled. The kind your car uses is generally CRS. It is the cheapest, weakest and most easily worked A36 CRS.
Submarines Hulls are made of a variety of steels depending on whether it's the inner pressure hull Usually titanium or other high strength steel or the outer hull (NON Pressure.)
All steel is initially "Rolled" into either sheets or plates at the mill. (differing thickness) Often times those plates are "Rolled again to form shapes.
Aluminum is, on a WEIGHT basis, STRONGER than Steel. Think for a minute about the wing spars of the 747. Not only do they hold up the aircraft and its load and fuel, they flex continually and have worked for many many years with NO problems. (there goes the beer can analogy)
I am afraid that you have been taken in by a knowingly misleading marketing campaign designed to play upon the fact that most American Truck buyers dont know A36 CRS from toilet paper.
The maximum takeoff weight of a 747 freighter is 875,000 lbs. Class 8 truck bodies and many other vehicles are made of Aluminum...It is plenty strong enough for a Pick up truck.
