Can you give us some measurements of the battery?
Most Coach batteries seem to either be Group 24, or Group 27.
The size will tell us which one it should be.
These are really common batteries, and any reputable battery vendor should be able to set you up with what you need.
Just make sure that he know that it's going into an RV...
EDIT: A chart with the battery sizes...
