In our old 5th wheel I did the same as a previous poster, got rid of the couch and replaced with 2 lazy boys. Wish I'd done it a couple of years earlier.
In our newer 5th I'm once again considering getting rid of the couch just for the additional space. RV couches are not well made or comfortable. Our newer one has a fold out bed and we slept on it once and that will be the last time. We purchased an Intex inflatable queen mattress in case we get guests. Otherwise I'd like to just have a card table with folding chairs so we can do puzzles and have workspace when needed. (we spend about 4 months in our 5th wheel during the winter down in FL)
