Actually I have a set of axles off one of those dumpers sitting behind the garage. I fabbed up the frame and spring hangers to fit them, but then found I couldn't get it out from the back yard. Those were the tyres being delivered to my house. We plan on mounting on custom beadlocks and once the 1012 Mann is installed with the Hendrix Skunkwerks crawlers boxes, we'll just use it to drag the house out of the way to get to the street. This should be ready by next Christmas, but given the track width I'm not sure what trails I'll be able to run. Actual tire size reads as 140" x 36" x 36" - syping them took one month.
