Thanks for you suggestion, I thought about those, but looked at the Vitrifrigo version and ruled them out, mainly because they are too deep for the units so wont fit and secondly is seems they waste quote a bit of space due the the runners, and I felt that, access seemed a bit restricted and they loose all the cold air when open. I stand to be corrected.Indel B Cruise 49 drawer fridge, was expensive but so far been worth it.
