Insulating dash air ducts.

[HARDY212]

I have a Forrest River Georgetown 369 XL and the ac ducts occasionally water drips from them on the passenger side. What type of insulation is normally used to prevent this happening? Any and all replies are welcomed.

It may be coming from the condenser drain under the hood on the passenger side. Add a piece of 1/2" ID tubing to the drain outlet secured with a hose clamp, route so drainage go to the ground. Air when traveling sometimes pushes the water inside on the passenger side, mine was doing the same thing and this fixed it.
