We have done a lot of changes over the years here is just one example that may help. Decided that the sofa was not comfortable to sleep on and when folded out you could not get to the door or around it...(jack knive was obviously called for here) very uncomfortable spring loaded mattress. so took it out and for years used an inexpensive futon bed that could stay made up with all linens and folded back to sofa for day time use in about 1 minute. Very comfie and full size Queen Bed good for naps as well......Decided oh lets try a flexsteel magic sleeper sofa they look soooo nice. Had a great RV furniture guy install at over $1,000.00 bucks Ultra leather and matching etc...and discovered was way to firm the foam was like a rock to me.and about 1/4 difference on each side. So being the creative problem solver I used folded blankets to first get both sides even, then bought a 4 inch foam covered pad. Since it was my bed each nite it stayed in the "made-up" down position all the time even on the road. The cushions were always in the way and I finally stored them underneath the coach. The four inch foam topper was huge even when rolled and secured with bungie cords so since the sofa would not fold back with all my "comfort" items it remained a huge day bed so to speak..wonderful for kids and grandkids but seriously wish I had not gone there. So for resale value yes the new sofa was just like new! but in my humble opinion I hate RV sofas for sleeping and for seating.
