2 What size air conditioning unit do I need?
As a rough guide, for different sizes of Motorhome, Campervan or Caravan
A 5 metre vehicle requires approx 1kw of cooling capacity
(The Dometic CA1000 air conditioning unit requires only 450W of power to generate 1kw of cooling capacity – Suitable on all European campsites due to low starting power which is less than 3 A)
A 6 metre vehicle requires approx 1.5kw of cooling capacity
A 7 metre vehicle requires approx 2kw of cooling capacity
