This is our largest model and it's perfect for Class A motorhomes and larger RV's. If you have a family of 4 or more and want a well defined patio space at your campsite, this is the mat to get. Our 9x18 patio mats weigh just about 15 pounds yet fold compactly so they're still easy to take anywhere or stash in one of your RV's storage bins. This mat will fit a full sized patio table and chairs and still have room to spare. On larger motorhomes, this mat will run the entire length of the area under your RV awning. Perfect for family camping and larger patios!
