powering a slide on camper while away from caravan parks

milo ,

You won't power all that lot from Solar -

If you ditch the Microwave and the Aircon you might just be able to do it -

If the fridge is 3-way use gas as 12 volt is very very demanding ...

If you want more info there is a solar Calculator available to download

from my website ( see below )

As already said - forget running the microwave and aircon from battery. A 3 way fridge has the advantage of running on gas when you are stopped, but a 12V fridge is better provided you have the battery capacity. Everything else, lighting, laptop, charging phones, cameras, etc can be run from battery power. A dual battery system would be very desirable, and depending on the fridge one or two solar panels too. Starting to add up to serious $$$$. As already suggested, might be worthwhile starting in a small way and then expanding when you have experience with your rig and how you use it.

Suggest check out our blog Electricity for Camping on this site. This discusses in detail batteries, charging, usage, sizing, and lots of stuff which may be of direct relevance to what you're thinking of doing.
