Firstly and bluntly, this is a typical, noncompliant permanent installation....frankly illegal....definitely presents unnecessary dangers.
I am not up with the specific current provisions of the caravan wiring standard Its been a while since I read it BUT.
It is generally not considered compliant to simply have a piece of flex with a plug on it disappering into a wall cavity in any installation.....noncompliance 1.
This power point, is it double pole switched..bet it isn't..noncompliance 2
Is there any circuit proterction fuses, breakers fitted to the installation..bet there isn't...noncompliance 3
This extension cord and powerpoint, is the earth circuit in this arrangement bonded to a central earth and to the metal chasis of the van....bet it isn't...noncompliance 4
If you pass an extension cord thu a hole in a wall, that hole must be big enough to allow the plugs to pass thu, or it ceases to be an extension cord in the eyes on the standards and the law, as it is no longer portable and would have required "electrical work" to be put there.
As soon as there is a power point screwed to a wall, there is an implied expectation of permanence and compliance with safety needs.
Most people will look at it and say.."its a power point" and think no more of it and treat it just like at home.
The inverter may be screwed to a metal bulkhead, but we can not be sure that the metal bulkhead and all other metal in the caravan is bonded to a central earth and also to the chasis of the van.
Neither can we be sure that the connection between the metal body of the inverter and the metal pannel is adequate or reliable.
Appliances.....that is any portable item that is conected by a 3 pin plug and cord are not part of an installation.
The above is just a quick assessment of the situation.....let me look directly at the installation and put a few standards in my hand and I could get a hell of a lot more picky.
One other issue that may or may not be mentioned in the standards BUT is a safety issue is having a source of electrical supply switched from a location not accessable from its place of use...IE the inverter in the boot.
Frankly there are two options.
1 is to use the inverter as a portable device ( my preference) or to mount it on an insulating block inside the van close to the item being supplied...this requires no licence.
2 is to have the system installed properly by someone who knows the specific regs and issues involved.......your best option.....this requires a licenced electrician.
