You are the only one who actually knows what is right for you.
I found having the portable at ground level was unsat because the trailer was in the way part of the day so the whole panel and stand had to be moved way over to someplace else. Depends on the camp site if you have room. (Assumes no theft problem too)
The length of wiring where the batts are in front was a limitation. Longer wires don't get the trailer out of the way, with the awning on one side and the slide sticking out the other. So my portable goes on the roof. I arrive, haul them up with a rope and set it up, connected to the wires going down the fridge vent. Before leaving it all comes down and goes on the bed for travelling, where it won't get smashed, along with the TV set.
I find 250w flat is loads and loads of solar for how we camp in summer at 70AH/day. Even so I tilt them up facing South (being portable and not nailed down to the roof like some have theirs :) ) to get more AH for those partially cloudy days we often get.
We don't even bother to take the solar with us for winter camping as we don't have an open area then like where we go in the summer, just provincial parks which have their sites in the woods.
If I had the solar gear you have now, I would not need the second panel or a controller for it, just the 230 and the one 20a controller. If you camp in the open in the winter so you only get half the sunlight as you do in summer, then the second panel might keep you even, don't know.
