I've been thinking in the same vein. Heading to Virginia next week to pick up G-daughter for the summer and my turtledog won't fit in the trunk. Guess I'll just have to hang down beside the creek. Someone had questioned about hingeing the toprail which could work for the legs. One of my thoughts was making sleeves out of aluminum tubing. Square in my case for the 2x2 wood legs on mine. Maybe 10" to 12" pieces would allow enough bury inside the sleeve.
