Our motorhome had a pedestal table that could go in front of the sofa or other locations. We found it inconvenient to use. It was fine for eating, but not to leave up. It was long and narrow, and always in the way! On our last trip, we left it home and used a portable table instead.
After searching unsuccessfully for a different table, I finally made one. It seems to work much better! It is oval, 22 x 27. (The other was 38 x18). By mounting the base off-center, you can rotate the top so it is over your lap for eating, but further away when just relaxing. Not nearly as heavy or bulky either. Seems to work well for us!
