Most people have attacked the sound issue from below, not above.

I added fatmat to the underside of the doghouse and under the dash.

I put one layer of Dynomat stuff (50 mill thick asphalt base material with thick alum. foil) then one layer of Fat mat (3/4 inch foam with thick alumium foil) under the dog house. (lots of diff name brands on Amazon).

And then 1 Dynomat and TWO Fat mat under the hood/firewall areas and anywhere else I could stick it too. So every square inch is covered when you look under the hood and then some.

It made a signifcant diff in sound and heat (no heat transfer now) inside the RV.

A dash mat might Help a little but I think you need to start under the hood area and dog house first.

I started to search dash covers as a way to nullify the reflections that bounce from the windows as evidenced in your photo. Custom (at Quartzsite) was $250. Nope.
I'm still thinking on it.
I'm wearing trifocals now but my hindsight is 20/20.
Bilsteins and Sumos front and rear...HUGE! FatMat and Hoodliner...HUGE!
Hellwig sway bars F&R, 235/85 Hankook ATM, alignment...HUGE!!!
Battery watering, 260watts Solar and BigFeets to make life easier.
