Hi Cliff what is the weight of the roof mounted part of the Blizzard as that is what has prevented us getting one fitted. Apparently the roof on the Lunar Lexon needs to be streghtned to accommodate the extra weight.I had the Swift dealer fit my Blizzard 1100 two seasons ago. The lightest in the range and very effective. If you get one the best method on sunny days is to close the blinds and leave it on. In the heat of 2006 when it hit 37c coming back to the van was like walking through the frozen section at the supermarket. Not much use for it in 2007 so far though.
Changing my van next month so if you are still interested in getting one pop a reply up and I will give you a contact number. New van comes with one as standard.
I have all the brochures and instructions for installing. Trickiest bit is running the 240 supply to the unit. Wouldn't pay a dealer to fit it again though is it is real easy going by the instructions.
The cost of the Truma in comparison was just a bit to high to warrant purchase. Does yours allow it to circulate warm air in the winter and what was the approximate cost of fiting? Our concern would be the noise disturbing neighbours as they have come away for a peaceful weekend.
