Found the patio mat to be a great thing. Helps keep dirt out of the trailer. Ours rolls up tightly enough to slip into the storage tube mounted on the back bumper. Our Chalet Aframe is now configured for one bed, and last summer we had a third person along, so she slept in the Tetragon tent. Forgot to pack the piece of Visqueen we put under the tent to protect the floor. Instead we set it up on the patio mat, which proved to be a big improvement over the plastic sheet.
