Experience of Aircon Unit?

Thinking of getting a roof mounted aircon unit for our twice yearly visit to Spain. Never needed one previously having had large motorhomes (no aircon) with several overhead skylights.We downsized to the new Symbol Plus Campervan, We only have one roof mounted opening skylight and a rear extract/blow fan about 10” rear end in the kitchen area. Any of you folks recommend a suitable aircon unit or are they all noisy and juicy to run?

We removed ours which was standard equipment on our Sussex because it simply didn't work (it was 8 years old when we bought it). We don't travel to Europe so hot weather isn't that much of a problem for us. We replaced it with another rooflight, so we have three now. Aircon only works when on hook up so of no use on Aires or on non-electric sites.

We had a Dometic Freshjet 1700 fitted to our Eton which is just under 6 metres for £1599 at Notts County Campers in Sutton In Ashfield. We were in Greece for the last 2 Summers/Autumn and can't imagine not having the A/C at night, it is a little noisy but you soon get used to it especially when you've had a few ouzos or sangrias. As Paul says they only work on hookup so running costs are immaterial, just make sure the power that the one you buy uses is low or you may trip out the hookup.

Thank you.

Plus one for the Freshener 1700 on our Nuevo. Can't imagine being without it. We don't need it at night but it is invaluable in hot climates, especially to keep the van cool when cooking inside.

I have had dometic and truma units fitted to vans, the last 2 were truma ,in my view way better,quieter technically better as heating is provided by reversing the air con (heat pump)
Had load of trouble with dometic heating is provided by an element this is old school and not efficient.truma every time for me.

The other thing is keep windows and doors shut,close the heating vents in the cab,they won't Air-condition the world.
