I built myself a full size off road steam truck. Had it almost ready to run last spring, will finish it soon. Just some of the automatic boiler controls to finish and insulating the steam lines, (so I don't get burnt on them) And then there will be accessories. Like a generator for running power tools and a hydraulic log splitter mounted on the side. Always wanted one, finally collected and built enough stuff to put it together. Started with my old '81 dodge 3/4 ton 4x4 truck.(retired to off road and then I didn't use it much) an ofeldt boiler and Westinghouse high speed engine built by ACME in the 1920's I think. (ebay find that I couldn't pass up for $1000. most any other old engine of that size is priced at $4-5,000 or better) https://www.flickr.com/photos/25229322@N04/36872246870/in/dateposted-public/
