How have you run the cabling inside the roof? Looking at these panels with rear entry myself, and there is not enough space behind the tent on my reimo to run the cabling outside of the canvas, so i've got to go inside. Concerned it's not going to look great cutting a 40mm hole out of the headlining.
Then i've got to either drill through the frame of the roof or the furniture board at the back of the bed.
I have an Austop, so I can't comment on how the head-lining is attached in a reimo, but I'm confident there should be enough depth between the roof and the lining.
On this photo, you can see on the left there's a thick layer (most likely insulation), onto which the lining riveted in my case. That gives more than enough space for the panel's back box and routing the cable where I wanted it to go.
Other wires are for an LED at the front of the roof, over the cab.
Then the I made sure the cable exists in the corner of the lining when I re-riveted it in place. That's just before I did that.
I also routed the cable on the left of the strip of wood, back of the roof aluminium profile, and down in the real pillar alongside the loom that's there.
That gives a better view, before the bed board was reattached
And once all done with the bed in place, you can barely see the cable at the far end
View from inside: hidden away!
In any case, all of this is over the bed board, so if you have one, it will not very visible unless you crawl to the back of the "upstairs"
