Before I did mine I read-up on a few "audiophile" how-to forums. There were, of course, as many opinions as there were members, but the consensus seems to be that you need to focus on the inner door skins, basically replacing the factory plastic vapour barrier. Cover all the holes in the door as described above.
You will be somewhat limited on where you can place the sheets inside the door's outer skin, because things like the window regulators get in the way. I focused on using the acoustic sheeting behind each speaker, as recommended in one of the forums I read.
FWIW, 100sq/ft is more than enough to do your entire truck, including the cargo area, with enough left over to line the outer door skins near the speakers and any other easy-to-reach areas. I "doubled up" on large flat areas such as the cargo area floor and the footwells. 100sq/ft won't be enough to do the roof, but that's probably overkill. Still, if I ever have the need to re/re my headliner I'll probably dynamat the roof at that time. Couldn't hurt.
I also went to the local race shop and bought a roll of sound deadener for the footwells. It's basically asphalt sheeting. It's not adhesive, so it can't be placed on vertical surfaces, but it's ideal for floors. Fits between the Dynamat and the OEM carpet. Way cheaper than the adhesive stuff.
BTW, this is the adhesive stuff I used:
B-Quiet sound deadening materials - B-Quiet Extreme
Worked out to be CAD$1.40 sq/ft at the price break of 100sq/ft. It's good stuff and less than half the price of Dynamat.
