...Ordered a 600BF kit of Touch n' Seal and we will see how it goes.
It has an R value of 7.12/inch so at 1.5" thick I should be ~R10. Most importantly, I can fill all the voids left by the factory nimrods, which should make the AC's and heater more effective, as well as reduce road and outside noise. ...

Let us know if that 600BF is enough to do the whole thing (walls and ceiling). At 1.5" thick it will only cover 400 square feet. The ceiling itself is a little less than 200 SF. 600 BF Might or might not be enough to do it all. That's one reason I suggest to people that they leave the OEM stuff in place (maybe shave it back to 1/2") and just add whatever it takes to fill out to 1.5"
