4/0 or 120 sq mm cables are extremely hard to work with. Relative to two half the size.

So that I understand better, do you mean using 2 - 2/0 cables from distribution to each one of the 2 positive and 2 negatives on the Multiplus?

I have longer than desired cable runs in a tight class B rv. In order to route the cables I used dual runs of 2/0 ultraflex welding cable which gives lower voltage drop that a single 4/0 cable. I found these online at a discount because it was left over from end of rolls. It works well and very easy to route.
