It depends alot on what your CCC is and what the difference is between the existing countertop and the 'small' piece of granite you'll be using. The difference probably isn't much more than a few cans of pork & beans.
3/4" granite countertop is around 12.8 pounds per square foot. Typical household laminate is around 3.5 pounds per square foot, so the difference is very roughly 10 pounds per square foot of countertop. It adds up pretty quickly unless the counter is tiny (which is unfortunately a very real possibility in an RV).
