We had Adco's best one whatever the name Sunbrela or something.
We padded the corners well.
When the wind blew it billowing and stretchingthe cover and we had to retighten the straps underneath. I mean every day or twice a day.
When we removed the cover the corner padding was wet and green growth there and elsewhere.
We were sheltered from the worse of the sun.
A Neighbor down the road has his covered and the plastics sorta melted and the wall covering/paper came loose and so on from the buildup of heat.
We also had the wind billowing the cover and providing some release of heat I suppose, unintentionally.
Two winters mostly is all the sue we got from it. Repaired two corners and another tear during that time with the provided pieces of material and glue.
I don't remember is or how long a warranty was for but after the second season it was scrap.
Best idea is to store it inside somewhere until you can build your own building like my multi talented Neighbor did with a prefab metal building plus extra material to make it taller and doors on one end plus work he did to keep winds from tearing it apart. It survived with two tornadoes. We usually never have even one. By there the otherr day and still standing.He put 1 3/4 rock over soemthing liek cement powder and another layer rock packed down with a roller.for the floor. Concrete is nice but he won't have to deal with cracking.
