Yes and No.

I use products from CAD Distribution https://www.deadening.co.uk/collections/dodo-mat which work well.
On the inside of the cab I use the DEADN mat. I cover the seatbox and lids, the sidepanels (between the door and the tub) the floor panels and the bulkhead up to the dash.
On top of that I use the Dodo Super Liner 6mm with the rubber mats/carpet etc on top of that.
Under the seatbox and all round the battery box I use Dodo Thermo Liner 7mm. This can also be used in the engine copartment on the bulkhead and under the bonnet.

Other areas to fit a combination of Deadn mat and Thermo Liner is in the doors, on the cab roof and the tub floor and sides.

Flashing tape inside and out, camping mat on the floor inside the box.

Same as TheQ states above, I never told the wife I had done it first trip out she asked, have you done something to make it quieter? so it does work!
I only did the underside/insides of seat box/lids.

I can imagine the seat box/battery box acts like an amplifier ? I'm all bare metal at the minute apart from floor mats and tunnel, got me thinking now.

Tbh I like the bare bones looks, also makes repairs/cleaning eaiser.

I just bought two rolls of this and the seat box will be getting done with it. Obviously don’t know the result yet but it seems to be good stuff. When I added it to the basket it gave me a £15 discount on the list price so I bought another roll.

Any bare metal surfaces will benefit from soundproofing.
ln my experience, if a panel or bulkhead etc already has some soundproofing, adding extra soundproofing makes little if any difference.
l've tested this with a db meter on my 110.

I used closed cell foam when I did my rebuild years ago. Same stuff as camping mat probably. Then I put the original carpet back over it.


I put a couple of layers on the bulkhead

I've got this in mine. Thankfully I acquired it for free but what a difference it makes, it's very heavy and backed by thick foam. Lot of money to spend but if you had it spare I'd say its worth it

Bulkhead soundproofing is what's made the most difference on mine, made a difference of 10db at motorway speeds. Went from 90db to 80db

If I recall from my NEEBOSH course at work, 85db is the point where ear protection is required in the workplace….or risk permanent hearing damage

And in addition , if you add in bone crunching suspension and white knuckle ( white finger being the precise term ) when driving in excess of 70mph , we would also need to introduce frequent rotation of drivers and vibration suppressing gloves when taking the wheel ( section 21 of the driving the landy at speed act )

You’ve been on the course then !!!

I used Silent Coat - easy to apply and made a remarkable difference. I did the seat box and rear load area.

Good price to....
