Better late than never. DW and I finally have crossed paths due to work schedules. Here are the pics of our kitchen toppers.
This is both the sink cover and the stove topper. The stove topper is a wood cutting board with a rubber non-slip bottom. It stays in place even when trailering. The sink cover has diagonal adjusters on the rubber feet to custom fit the basin. Both are removable to use elsewhere. Pic #1 is both covers.
Pic #2 - Sink cover in place.
Pic #3 - Bottom sides of both cutting boards.
The stove topper came from Camping World and included a plastic cutting sheet. The sink cover we bought from our dealer (Ballantyne RV) when we bought the 2499. Hope this info helps.
