As long as I have the space and weight capacity I'll never go back to sleeping on the ground (or floor if rooftop). I took notice of DAA setting up and tearing down on our Wendover to St. George trip and have adjusted my camping gear accordingly. I opted for the 8x9 Kodiak over the 7x8 Springbar since it gave a little extra room for two cots and has a second door. It is a heavy pig, though, about 68lbs. I also changed out my cot and table for old time, fold flat models. The ones that fold into a tiny bundle take 5x longer to get set up or torn down. I'm an old fart and could not believe how much I liked being able to swing my feet out of bed in the morning and sit (some day maybe I'll have a coyote fur rug for my tootsies like DAA) and then to stand fully upright to put on my pants.
I'm with DAA on how fast the Springbar/Kodiak is to set up. Drive a few stakes, spring the top, raise the roof. Not slow at all. Just not something I'd want to pack in for a mile or more.
