I recently bought, from an internet advert, some 'waterproof seamless adhesive hooks' and have been really impressed.
They hold up to 10kg,adhere to any flat surface, can be removed and repositioned without leaving a mark and are cheap.
Have distributed them generously throughout the van.
Available on E Bay using the search term above.
Just a note, don't forget to remove the backing first, do not ask how. I know this.
Secondly, the metal surround on the door catch on the semi-circular door under the sink has always been cock-eyed which, let's say, has irritated me over the years.
I had always thought it was glued on but took the bull by the horns today and prised it off, readjusted it and pushed it back straight.
I know have peace of mind, so if yours is on a slant ( ooh er missus) the fix is easy.
