Soundproofing?

[ELVIS]

What have people used and what worked/didn’t? 

previously have only gone for 25% coverage of side panels/ doors with silencoat. Have also done front panel and dash. 
 
 Ideas regarding floors and under seats and engine bay. 

have a LLE with factory sound deadening. 

ideas?

Your LLE already has a lot of soundproofing, the cab floor, passenger floor area and continues outside underneath the rear raised area above the gearbox and the engine inspection hatch. The D pillar areas and between the roof and headliner also have enough soundproofing.

I know it’s got all the factory stuff but at full chat it could be better.I know it will never beat a modern car but was thinking of what others have done to improve theirs. 
 Don’t mind ploughing a few hundred quid into it if it helps

Add weight to big drum-skin panels with a heavy butyl or flashband etc., to change the resonance, then add something soft to absorb sound as well (and provide heat insulation if you so wish). Wind noise is also useful to address, especially round the door closures in the cab.
Something like this

fitted in addition to the factory seal on the front and top edge of the door had a big effect on mine.

Or just drive faster and leave the noise behind…
