Hi all.
Graham be carefull, on-site staep down transformers are 55-0-55 not 110-0-110. You are correct that large 3Kva step downs are available in IP66 cases and if you know they are well priced.
When i brought my 358V back fom Fl last year and then moved her to Portugal, i installed two 3Kva step downs as i have two insputs A\C and Mains, i then installed a 110/230 step up in then then Coffe machine area where i have the Trac Sat Tv/decoder and BlueRay( remove Coffe maker and had Four Winns make me a new doors for the coffee maker area and also the Tv (center) i moved the new 32" to the back head liner my the steps). From this i also have a dual outlet for Kettle etc.
The only piece of equipment that did not work on the step down was the Ice Maker in the rear ( uses a analogue step A\C motor)
The A\c works fine as does the batttery chargers and stove fridges etc, all lighting is 12V.
I would like to add i spent about £4,000 on a CE plate/RCD Plate, this makes the import completely legit as well as paying the VAT on import.
I have owned my 358V since new in Us Aug 08 and would be happy to help anyone with questions on import, i learnt alot!!!!!!!!!!!!! buy a trailer in US!!!!!
