'02 Southwind 32V F-53. As I was checking the engine oil, I looked up to see the underside of the fiberglass dash panel. This horizontal panel is approx. one foot deep and extends the entire witdth of the front of the coach. My first thought was "where is the insulation?" I would appreciate any suggestions as to how best insulate this area along with any gotchas. I have been leaning towards canned spray foam.

I have a similar area on mine. I have read somewhere that the spray foam, while seeming to be a great solution, is very flammable even after applied.
I think that the auto parts stores have some type of under the hood insulation that you can get. I may get around to doing that one day, but for now, please keep us posted as to what you find and do, along with the results.

you can get insulation pads at commercial truck dealers, like what is on the underside of your hood of you car. This is a foil backed insulation that is fire resistant hope this helps. regards

why are you looking to insulate it? it doesnt seem like it would cut down on interior noise.

I work with one part foam all the time. You won't get it to stick.
You can also get fiberglass sound pads from west marine. Foam Rubber pads from McMaster-Carr.

Thank you for the heads up on the foam. I will go for the pad insulation.
The area I want to insulate is the underside of the flat horizontal part of the dash that starts at the base of the windshield and extends towards the rear about 1 foot and runs the complete width of the coach. The windshield defroster vents (2) come out of this panel. From the underside it appears to be thin fiberglass (it will flex with slight pressure).
I hope a quality pad insulation will insulate the noise from the engine fan, along with the hot or cold air in this area.

Original OP you are correct, in fact mine is probally closer to 2 feet deep from windshield back to the fire wall.
It stands to reason, when we are in cold weather, the windshield really frosts up. A) because it is not an insulated double pane class like all of our side windows.
B) with all that cold transferring up, insulation will be a great idea, both for the sound and insulative value.
Thanks for a great idea. Gene.
