    Once again some top reading. And if you stick to those future plans I'd definitely follow cuppas advice.
    If however you are currently doing just short trips a straight isolator is still an option and when time comes with the camper trailer add the dc-dc charger to that.
    A little more expensive but it gets you a dual setup cheaper to start, then optimum charging in the camper when it arrives.

    I personally went an isolator setup with jump start override.
    Use 25mm2 welding earth wire to join the batteries. Got 6mm twin core running to the back for the fridge and other bits..
    Now for the fun fact..
    It cost sub $200... Lol.
    Redarc isolator is $120 ish.
    Cable $20..
    Split conduit to hide the bright orange cable.. $10

    Battery.. Free.
    Check out some heavy industrial joints like truck companies, or earth moving joints.
    Most machines run 24v and as soon as the batteries look like dying they change em out.
    Now if you find a place grab a couple as you may get a knackered one. But the one I'm using now can carry my fridge and camping lights for 2 days by itself.
    Can't complain for free.
    And like I said, save the cash for when you do get the camper and then setup for your longer stints and lash out for more top end gear..
    That's my opinion anyway..
    Cheers
