Some folks have removed the interior paneling in the 'snout' and have 'insulated' it for better temperature control. They have used fiberglass or the silver bubble wrap material. The butyl tape might be an easier and better method.
BE CAREFUL with the bubble wrap. You want the stuff that is designed for this not the standard stuff that you find at home repair stores. The home repair stuff is silver on both sides BUT it is plastic in the middle. After a few minutes you will start to smell it melting and a few minutes later the smoke will start. I started a motor home one time with the plastic stuff and could not figure out what was happening, got so bad that I had to shut it off and air it out while I was looking for the cause. Took the snout off and bingo, a few minutes removing the stuff and all was fine.
