We have a 3100 with a slide. I had our local boat cover man make slip over covers with velcro on the bottoms and handle/straps on each side for easy carrying. I also had him put velcro straps on the sides so that the chairs can be snugged together in the upright position for travel. We carry them immediately behind the driver seat, and the slide, when it is retracted. It works perfect. They ride well and the covers are color coordinated with the leather on the driver/passenger seats.
