I have just got a kitchen bin for the caravan, this is the sort you fit to the inside of the main door, comes with bucket, lid (hinges on fixing bracket) and said bracket. It states its for an Elddis and fits on where the elasticated nets go. Now the screws that come with the bin don't look up to the job and I may want to go to a fatter screw but what I want to know is what am I screwing into. Are doors hollow, will the plastic inside panel hold up to the job, has anyone fitted one before. Any advice welcome.
