The scuttle is basically the area at the base of the windscreen/back of the bonnet. Typically where the wipers are mounted. Sound deadening here and the bulkhead behind the engine will go a long way toward reducing engine noise in the cabin.

thanks
I used the heaviest gauge Dynamat as I had some left over, it doesn’t make much difference but only takes a few minutes.
I think it was 1.6mm from memory and I covered it all and it wasn’t really any different.
The front wings on the other hand ring like gongs, access from behind the wheel arch liner.
They are easy, remove, clean, cover the back face with 10mm self adhesive foam, press back in place, take and impression of the contact areas, remove and cut out the contact areas, refit with slightly longer screws.
One at a time unless you have an excess of jack stands

Thanks very much for the reply. It looks easy enough to diy it at home (if you're referring to under the bonnet sound deadening)
I've got the front cab mat up at the moment and debating whether to put some sound deadening/insulation on the floor there before I lay it back down.
Have people found it's made a big difference?
Materials wise too, I've some leftover dodomat deadn, but wondering if it's worth ordering some dodomat duo for the job instead?
if so, any issues getting the duo pro 7mm thick layer down under the cab mat? or better to shoot for the non-pro 4.5mm duo instead?
Thinking I may as well lay the same stuff underneath the rear load mat too (planning on keeping the OEM front cab mat and rear load mat as my flooring for the foreseeable)

There's never a black and white difference with sound deadening apart from maybe the THQ panel van video on YouTube but I've put Dodo products under the wheel arches and liners, front wings, bonnet, scuttle, doors/doorcards and tailgate and can now tell how much wind noise the camper produces at speed and can actually hear the stock radio.
Afternoon all, does sound deadening with Dodo mat in the scuttle pose any potential issues withh water at all? Im considering doing mine but i know its going to be a right ball ache considering the amount of wax oil i put on there last year!
It takes a lot of preparation. I used thick Dynomat as I read the adhesive properties were stronger than other brands, it appears to be better than Silent Coat, never used Dodomat. Just using butyl alum’ sound deadening won’t make much difference, I used 35mm Sound Buffler closed cell foam on top of the Dynomat.
It’s not a quick job but it will have the biggest impact on cab noise levels.
