Air Conditioning for a Small Campervan?

Yes, I will try to get some advice from someone (any ideas who?) that installs these sort of air conditioners. Might have to contact the Waeco distributor and ask who sells and installs them near me (or in Sydney).

I also assume that the 1000 means 1000 watts.

The Landcruiser Bushcamper is a very small campervan, really a Landcruiser Troop Carrier with a higher roof, so I don't think I need a very large unit, as I don't think you could get a much smaller campervan internally than the Bushcamper. And I want to keep the power requirements for it as low as possible for possible battery/solar power operation.

Thanks,
