I have made a number of mods to my 2018 28BHBE, all inspired by this forum and many of them from BigJohnD. I haven't seen my most recent mod done yet so I thought I would post my version.
We didn't purchase our trailer with a TV as we have never had one before and didn't feel the need for one. On rainy days we play games with the kids or go venture into a town and do some shopping. There is limited counter top space in the trailer and I hated seeing the coffee maker taking up space all day when it was only used in morning. I also did not want to get it out and put it away every day, so the unused TV area seemed like a perfect place to change. Below are the before and after pics. I took out the swivel TV cabinet and added a back panel and shelves make the space more useful. The big area to the right is for the coffee maker and the bottom shelf on the left has a power strip for charging all of our electronics.
