Slightly surprised that gas had 4wd things. I can understand it for leccy or BT as they need to get to rural areas and up shitty tracks to remote locations, but gas is essentially urban where mains systems exist underneath streets, so they don't really need to go anywhere difficult. But googling produces some pics of gas landies and Mk3 transit 4wd, so they clearly had a few macho things - for winter emergencies??

Good luck and don't glue yourself to the table either.
