I’m going to install new sheet flooring in my 1998 Coleman Sea Pine. The PUP is stored nearby, and I’m taking it to my dad’s house for extra help on the floor. I have to purchase sheet flooring before I pick it up—the spec online states that my pop up has 130 square feet of living space. Does this include the space under the cabinets, or is it just the walkable area? I have to order a piece of flooring and I don’t want to come up short—130sf is 15 square yards of flooring. Should I get one more square yard to be safe?
