Last fall I bought a Cover It 12' x 24' pipe frame garage. The canvas was ripped in several places. It was 17 years old but the guy said that he had bought the extra heavy duty cover. A roll of 3" Gorilla Tape and I was able to repair the cover. A new 20' by 30' tarp over the cover kept it dry inside all winter. Total cost for the 12' x 24' dry storage area was $120 and 8 hours of my time. That included taking down the frame last fall and erecting it here.
Last Saturday, I ran into a guy up the road from me(at the transfer station which is our social center). He gave me a 10' x 20' Cover It garage that had a bent frame and disintergated top. It took 4 hours to disassemble it(many rusted bolts and distorted tubes. I figure to spend 2 hours to straighten the tubes(on my welding table) and three to set it up. For the summer, I will cover it with a 16' x 20' tarp. I figure 10 hours and $12 for this shelter.
I am pointing these experiences out to encourage others here, who like me, are on very limited budgets. There are all kinds of deals around, just talk to people. Good Luck, Rick
