After a small gas/electric fridge in working order. Prefer 3 way but 2 way will do if it's local and/or cheap. It's got to fit into a gap about 41cm wide. A bit of googling suggests suitable models are Electrolux/Dometic RM123, RM122, RM120. I'm based in North London, planning to go to Techenders and also fairly regularly visit family in Bournemouth/Poole. Thanks!
