2016 4Runner SR5

Today I installed this sound deadener: https://www.amazon.com/gp/product/B00URUIKAK/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1
I did the doors and the rear hatch. I'm sure a professional shop could have done a better job than I and I know there's probably much better products and layering to be done, but I'm on the budget plan. What I ordered was more than enough for the doors and the rear. I'll be taking a longer drive tomorrow and will have a good guage on if it helped much. I was pretty surprised to see next to nothing for insulation behind the door panels in my 2014 Limited. My K02's have about 16k miles on them and definitely are getting noisier as they go. I'm hoping to install this above the roof liner this Friday. Every little bit should help is my hope.
One of my biggest reasons for doing this was adding an additional layer to help with heating/cooling. There is no ventilation to the 3rd row which I do use for my kids. We've used portable small fans and put the middle pass through in the 2nd row down to help. I'd love to step up to a Land Cruiser/LX570 but the 4runner is paid off and kids are expensive.
That stuff isn't bad as long as you install it correctly. You absolutely have to use a roller and press every inch of it into all the body contours otherwise it really won't work as designed. I did my whole 4R also, inside door skins outer door skins, floor, only thing not done yet is the roof.
