Gazelle's T4 uses a hub frame that the brand says sets up in about 90 seconds, useful when a dog cannot wait calmly through a long pole assembly. The 78-inch height, two D-shaped doors, six windows, and removable 300D floor create a practical car-camping interior. At 30 pounds and 66.5 inches packed, it is bulky, and the floor seam, zippers, and hub structure are not dog-proof.
