Retrofit for dinette area

[Bratzwagon]

My husband and I purchased a 23ft ultra-lite travel trailer which has double beds that are the tent type that drop down on each end. It also has a sofa that makes a bed and the dinette area which is in a slideout converts to a single bed. Since we have had some health problems, and aren't getting any younger, we would like to convert the dinette to a larger bed. We eat outdoors most of the time or use TV trays so I don't think we would miss the table that much. I would like to know if anyone else has made this conversion, doing it themselves, and if they would share how they did it.

Thanks for any advice & happy traveling!
