Twin Slider Side Unit Wiring Routes

[Farnorthsurfer]

Need to get my first fix wiring in soon, the order has not been placed yet except for the Renogy DC-DC unit.
Habitation battery will be under passenger seat with DC-DC and fuse box.
Anyone have advice on the best wiring route to the rear units on a twin slider?
It looks like the floor is not the best option and I will have to go up the B pillar and back down the C pillar.
Any advice appreciated

I just routed it behind the b pillar trim and followed the vehicle wiring loom along the roof. You’ll need a spline bit to remove the seat belt to get the b pillar trim off
