We light sanded and cleaned with vinegar all of the paneling then filled in the depressions, after that we used drywall mud and trowled on a couple of coats then primered and painted.

Putting drywall mud on the walls of a mobile home is fine unless you are using the home as a seasonal get away. The cold of winter when the heat is off will cause the plaster to crack. If home is used year round it will be fine. Just wanted to mention this since a lot of folks just use their mobile homes for summer.
