I don't have first hand experience with dinette replacements , but inside you rig is always a place you can personalize. it does usually come down to time and cost , and is it worth doing to you personally. There should be RV interior folks in your area that might be able to give you specific information on costs etc. too. Furniture changes are done a lot especially in older units. Good hunting.
