I used a rubber foam type stuff I got from Amazon. I don't know how it compares with other material, but I would use something that has a bit of weight to it. The bubble wrap stuff is probably too light to dampen any drumming noise from the sheet metal. Many industrial plants use heavy vinyl curtains to contain noise, especially low frequency sound. The additional weight will take out the "clang" when shutting a door. I've heard of guys putting a glob of roofing tar in the middle of a door panel to do that, but that's kind of stinky and messy.
I used the stick-on rubber foam on the roof, inside the doors, and behind the gas tank, not wanting to change the original appearance of the rear of the cab. It's been many years since I've ridden in a stock AD truck, so can't really compare to what I have with mine with the sound deadening, but I'm satisfied with what I have.
