I have dark paneling on all of my walls of my trailer, any ideas?

You can paint them. Would you consider doing that?

Maybe paint a creamy white and sand spots so it looks farm house style. Paint in a satin.

Get a good quality primer that seals the wood so no staining comes through. Then paint.

I painted dark color paneling inherited from the previous owners. I used primer first, then a white paint with a slight hint of gray. It came out great, and looked fine, even with the vertical lines of the paneling. Relatives did the same thing with a knotty pine kitchen-dining area that had gotten quite yellow with age. Lots of white paint did the trick, and gave the room a nice cottage-y look.
