This is a black range cooktop bifold cover from Dometic

 Range covers add additional counter space and serve as a back splash, protecting walls from food and grease saving you time and additional messes to clean.

This cover is designed to mount to the countertop, not to the cooktop. It is roughly 1-1/2" larger than the cooktop on each side and 2" larger in the back. Review the below dimensions to determine if you feel this will fit in your RV.
