Heya,
Yes got a panel, just got back from bodyshop, so it's still all empty inside.
I need to sort the engine and brakes out first, then I'll start thinking about the interior.
I think I'm going with light wood inside like you, I quite like it. My slider has a louvre window, so it's a bit lighter inside.
It had previously had styrofoam insulation and dark woodchip boards inside, that was a bit dark.
I don't think I'll have material like doorcards inside the whole bus.
I got to get my photobucket sorted again too...
Good luck with your decisions, I like how it is now...
Wish my bus looked as tidy as yours, maybe one day...
