Fed up with sweltering in a non-air-con tractor? French company SNDC sells this self-contained, 12v-powered Skimo unit that is 72cm x 48cm x 25cm in size and will fit on any roof bigger than 40cm x 30cm. The unit, priced at e2050, comes pre-filled with refrigerant and can be self-fitted, but needs an alternator output of at least 100A. The company is looking for a UK distributor but the unit can be bought direct from the firm. See www.skimo-clim.fr for details.
