Fitted front Drive and passenger door seals:
VW only fit basic door seals there is no extra seal so you don't get that solid sound when shutting. VW want around £60-80 per door, Car Solutions do a neoprene D seal which works out at £25 delivered for 4 meters! Does the job and easy to install. We know have a nice "clunk" ha ha
Drop the oven about 1" to give a little more between the top of the oven and the waste water outlet
Fitted Fire Extinguisher to rear o/s D post
Researched changing to underfloor gas cylinder couldn't get 20 litre tanks when I started this! At least never came across them! Frees up a large space for more onboard storage.
