Probably won't help in your situation with two people and different sofa but might give you some ideas. What I do and how I keep it level for eating.
There are a couple of different places to store it during travel. On the bed, in the bathroom or if you are real careful between the slide and bathroom door. Do not ever operate the slide with it in there though!!!! Red tag it, pull the breaker or something to remind you why the slide will not extend. Need to protect the wall of the slide if you do this too.
Last two will take some strapping down.
That table is 32". Maybe just look for a 30" and two chairs to sit in the middle of the whole area. This one fits in the middle too but prefer this setup for me. I was looking for a 30" when I saw this one. I even thought of removing the forward recliner and putting a table in there.
Cut some cardboard the table size and see how it works for you.
P.S. Those seat cushions sure help.
