Upgrading to stainless fridge (cover?) & sink? Cost?

Check with Johnson's Surplus , Bontrager's RV Surplus and Tom's Borderline Bargains. All are located close to White Pigeon Michigan, they all do e-sales and have had sinks when we were at their locations. Another place that does Internet sales located in Elkhart Indiana is Factory RV Surplus we have seen sinks there also (we bought a Rv fireplace from them). We purchased sinks and several faucets for our Texas Room at our RV lot in Mission TX from Tom's and Johnson's.
