Also would have to go pure sine wave type in order to start fridge & fans easily. Correct??

You're talking almost domestic scale elecrical draw 200Watts is approx. 16Amps. Plus your "lighter loads" mama mia!!!!
The fridge will be on say 50% duty cycle and the fan... who knows, but with a nominal say 200Amps of battery power available and the inverter maybe 90% efficient with its own cooling fan drawing power then a couple of nights would be all you could expect.
The square wave inverters are usually a modified sine wave and will run your gear but you may need to quickly switch on off on....
As Alan in previous post suggests keep your eyes peeled for Bert the Dutchman his Daf truck is "very" distinctive when encamped it rises to 2 storeys and sides slideout, he retails all the requisite electrical gear.For a price he'll fit as well. There's always Frank Wagner on the Algarve as previus post

Assumed fridge to be 240v domestic compressor type, but if 3 way camping type then the boiler is on all the time. Even more power used.

Sounds all good then mate. Only going to run 70w fridge & 120w of fan all at 230v & only use icemaker on site power. What about the stereo? Come off the bottom of the leisure batterys or the starter batterys remembering I'm getting rid off the amp now. I'm thinking a 1500w inverter to give me plenty. Just matter of finding 1 in Spain. Will the alternator b ok with just yapping the headunit off the bottom battery as it is a small load?
Thanks again for all ur speedy replys

If you can find the 24VDC to 220VAC inverter, you will probably be able to also find a 24VDC to 12VDC converter at the same shop. That would then solve all your problems because all loads would be supplied from 24V and the batteries and alternator will thank you for it. If you get a 25Amp one, you might even be able to continue the process of damaging your hearing by using the main amplifier. If money is no object, get two - one for lights, pumps and other normal 12V loads and one for the music system.
(The DC - DC converters are cheaper than the inverters)

Maybe not but it is true that any motor will run better from sinewave. Sometimes they run hotter and noisier off square wave but there is no easy way to predict.
