I've had this garage for five years and I might get another two years out of it as it still looks good. I buried 10 inch cement building blocks into the ground where each tent leg goes and leveled the blocks. I then applied polyurethane caulk under the tent leg bases and fastened them to the blocks with masonry screws. To increase the life of the cover I apply Turtle Wax Ice (car wax) to the cover with a sponge mop on an extendable pole, a few times a year. This protects the cover from the sunlight and makes it slippery so it repels dirt, rain, snow and ice. I also installed vents on the back wall to keep the summer heat from building up at the ceiling and destroying the fabric. A friend of mine just removes the back wall panel in the summer and uses the garage as a carport. For the floor I just leveled the dirt, put down a tarp and covered it with patio stones with sand between them. Sure it's extra work but it keeps my vehicle out of the weather and saves on property taxes.
