Here is an option I took; we had a 127" slide couch covered in bonded leather which was shredding itself as we watched. I replaced the piece with modular furniture designed for a pontoon boat. I fitted pieces to arrive at 127" exactly. Advantages: low cost, modular, lightweight, will fit through a door, durable, different colors, and storage beneath each section. Looks new after five years.
Disadvantages: No recliners or fold out beds, Uncomfortable as is, I raised the back 2" and reclined it a few degrees. Good now, but doesn't compare with the leather recliner I have from Costco. Doesn't look upscale.
We use 2' x 4' plastic folding tables from Costco. The legs adjust for height so they can be coffee tables or counter high. We can sit eight people for dinner in a 31 ft. fifth wheel.
This is an option, most likely not for many, but has worked perfectly for us. We get a lot of compliments and our rig is generally the meeting area for our friends.
