I have a 2000 Monty but this should work. I am using one of those hiking/jogging water bottle holders that one wears on the waist. Just slide it over the center storage console, tighten it and it holds my drinks very well. I discovered this by accident...needed to place it with out laying the bottle on its side and I now use it like that ever since!
Just an idea...
