In my Blazer, I lined the entire tub and inside my doors with Fat Mat. Worked great at sound deadening with carpet over top. But not so much with heat reduction inside the Blazer. To solve the heat issue, I lined a portion of the engine compartment side of the firewall with Kevlar heat shielding, and ran this all the way under the tranny tunnel over the transmission. I also added more Kevlar heat shielding on the underside of the bed floor between the mufflers and the bed floor. This heat shielding greatly reduced the radiant heat that was coming through the firewall and up through the floor. No more warm/hot floor, and the A/C works much better without having to fight the radiant heat.
