Hemmingsblog had several posts on it, the final one unraveling the mystery of how this wild rig came to be. One J. Dennis McGuire, who was a pioneer RVer and had converted a couple of buses before, started this project after he retired, and finished it at the age of sixty-nine(!) He always liked Buicks, so that was the main ingredient on the recipe. The third axle is the driven one, and the 401 nailhead must have been working pretty hard through the Dynaflow transmission to scoot the 9960 lb rig down the road. The turning circle on this must have been massive.
ShamRockAway was one of many projects Dad did when he retired. When people ask him, Why? He would say, “Why not?” He was an inventor and motor home enthusiast since 1948. Dad bought a 1942 school bus and converted it to a camper as it was called back then. He also converted a 1958 Flexible coach in the 1960s and toured the United States with his family, Michael and Colleen. He was one of the founding members of the FMCA, at the first meeting in Maine. Other projects he worked on were a wind machine to generate electricity which he mounted on his house and a semi electric car.
Michael (son-chip off the ole block) designed and built the unique steering gear box that allows all four front wheels to turn. Other features: power steering, air shocks on the drive wheels (only one rear axle is powered), near equal curb weight per wheel, power plant from an Electra 225 Buick, 401 cubic inch displacement V8 engine, Dynaflow transmission, and eight wheels, two gas tanks, solid frame, two heaters, two air conditioners, weight 9960 lbs., tires L78 except “J” on the tag wheels, double core radiator, standing height six feet and length 28 feet to bumper.
