spring bar makes a fantastic tent. It is only second to one and that is the Kodiak brand. In an independent lab test Kodiak tested approximately 7% stronger as far as the canvas goes. Kodiak uses a heavy duty for that is almost twice the thickness and weight, and it has a welded seam. Spring bar has a thin floor and a sewn seam which can lead to water leakage. Kodiak has a superior screen that is much stronger than spring bar. Both use the same zippers, and assemble similarly.
