Further to my first post, and sorry to disagree, I would not use an auto electrician, the job you end up with will cause no end of problem and if you do have problems you won't know
where to start. As an example I used an auto electrician to install my electric brake unit and at the same time had him run wires through to the rear end for powering the fridge. For the fridge he ran a 5 core wire through, the wire gauge was woefully inadequate, the 7 pin plug was woefully inadequate, there were wires running everywhere (mostly just extras that were in the loom) and joins were just wires twitched together and covered with insulation tape. The terminals were crimped, broken and bare wires sticking out, but most of all it was just messy and untidy. I pulled the lot out and rewired myself - far better than the job I paid for.
Most campers who do their own electrical work started out just like you - knowing very little. Interest or financial considerations saw them designing and installing their own systems. It's the cheapest way and if something does go wrong you're in a pretty good place to diagnose and fix the problem.
Start with a simple system: single battery, solar panel, regulator, 240v staged charger, a few 12 volt sockets and a plug in digital voltmeter for monitoring purposes. As you learn more and your comfort demands more you can add more.
I started out of interest on motorbikes, then cars, then campers, then caravans. Having tried most everything I keep my system simple now, single large battery, solar panel with 12 volt genny for backup, hardwired, staged charger, LEDs throughout, enough sockets for everything, water pump, tank gauge and a hardwired, switched digital voltmeter.
