The Name brands IMO are sticky-er and have less odor (I have tried 4 diff brands over the years). But they all lose odor over time so no worries.
Cover the inside of your dog house as well as the ENTIRE fire wall and under your dash (access from under the hood). I was very impressed with the results on my Axis. I also found other areas to add sound and heat insulation over the years. It all adds up. Not as quiet as a DP but very livable.

YES! We were one of the people whose Vegas had zero insulation under the “doghouse”. We added some Fat Mat hood liner. I wish we had doubled up with dynomat like Road suggested but we might redo it one day. Even with just the 3/4” FatMat the improvement was noticeable. Just yesterday I took some of the Frost King duct insulation we bought at Lowe’s and installed it under the dash on the passenger side
inside the RV. Be sure to get the kind that is not fiberglass. I wasn’t up to the challenge of trying to install it under the driver’s side. There are a lot more wires and cables over there but I did slide some in between the accelerator and the side of the console. My husband started the engine and we were both shocked at how much quieter the engine noise was! We didn’t drive it so that will probably change it a bit.
I looked at trying to add some FatMat to the dash under the hood but it’s August in SE Texas. I’ll have to wait until it’s cooler. I’ll also probably have to take some contortion classes
seriously, how do you manage to get up in there?
Finally, can anyone tell me what the firewall looks like and where it is located? I have tried to research it for myself but have been unsuccessful.
Thanks,
