How about using construction adhesive instead of screws for mounting? The idea of blindly drilling into RV walls is not in the realm of things I want to try given how badly things can turn out, the adhesive would be stronger than the MDF once cured.
I think construction adhesive is a bad idea. Camper walls are usually thin plywood with a wall covering (wallpaper). So you would be attaching a cabinet to the wall covering and relying on its adhesive to remain attached to the wall. A better choice would be Molly bolts designed for thin material.
