I'm going to buy a portable shelter to keep my tractor out of the weather. I'm considering the 12'+20'+8' heavy duty deluxe model from www.sheltersofamerica.com or one from "cover-it". Does anyone have any experience with one of these shelters or the two manufacturers? Does anyone see the advantages or disadvantages between the house or round style? I think I want to go with the one from Shelters of America. Any info would be appreciated.

Thanks,
