We had an issue with small things on our vanity eg comb, brush, makeup etc so this is my solution which was made and fitted by our local caravan service guy. A shelf for all our bits and pieces and no need to put everything away on travel days.
We had a splash back made for our sink in previous van (16.49.1 2007 model) and he did a superb job with that also. That shelf was $220! Any options we could have come up with we're tacky. This will be a bonus if we ever sell van.
