First of all... Welcome rdrose2499!
My wife and I 100% relate to your dilemma as we missed having a dinette in our previous motorhome. When ordering our PC back in 2007, a standard dinette was a big requirement for the very reasons you state.
About your 2022 2552 with a slide-out, if you can work it out with the factory, and are willing to spend the money and time, consider having Phoenix reconfigure your PC. If you know a skilled cabinet maker, consider hiring him for the project.
If you have a pantry between the fridge and the couch, that will need to be sacrificed to provide adequate room for a dinette.
