We've recently become caravanners and have toured europe extensively. We've found that at night, particularly, it can be oppressively hot in our caravan; have you ever included a comparative study of air-conditioners suitable for caravans? If not, can I suggest that you make this the subject of a future article for your magazine? I suggest that the critieria include noise (dB) , cost, cooling efficiency, power-to-ampage commonly available on caravan sites, ease of use, portability, size, weight and durability (incl guarantee period). This is not an exhautive list but covers the main points. Regards Tony Copage.
