Which double pole double throw/ 2 way changeover relay? advice please

You've probably already considered this but the onboard charger complicates things too.

Have tried a real world test of the microwave? I've recently fitted a 1200watt inverter with a dedicated socket for the microwave, I have to unplug it from the mains socket and replug it into the adjacent inverter supplied socket. I've tried mine which is only a 600watt (cooking power) microwave and it pulls @120 amps . Luckily this will only be for 60 or 90 seconds.

Yes, I've actually got mine working as I hoped it would. Of course I need to monitor how much it's taking out of the batteries (any simple to install suggestions/recommendations please??) to make sure the batteries can cope with what I'm doing.

Ive also now re routed the cables supplying power and aerial to the TV setup in the bedroom area using the original fittings, so it matches what's already in the van.

The bracket and 12v supply dont interfere with the cupboard opening. I won't be fitting 240v supply for the TV as I will just run it on 12v all the time and it means one less cable to squash into my 'man drawer'

Easiest way to implement an automatic change-over is to use a Finder 62.82.8.230.0000 change over (CO) relay and wire it up as follows:

L from inverter to pin 1
N from inverter to pin 3
L from hook-up to pin 4 and pin A
N from hook-up to pin 6 and pin B
L from motorhome consumer box pin 7
N from motorhome consumer box pin 9

Default is 1 connected to 7 and 3 connected to 9 (I.e no hookup connected so power is taken from inverter, when hookup is connected it puts power to the coil thus throwing contacts so 4 is connected to 7 and 6 is connected to 9.

The Finder relays are very good quality and are supplied by Dometic with their generators to use as a change over relay.
