Body will eventually be a pottery studio for my wife. But it is on a Freightliner motorhome chassis with a 5.9 Cummins (in pieces) and a MD3560 Allison. These will be coming out and sold off. All the electronics modules etc will fit my trucks. Also it has an air ride front and rear suspension which I may use on Big Red to allow for variable ride height when using on/off road.
Really though the main thing I actually bought it for was the pottery studio.
Now I am fairly lucky in that I have a wife who actually appreciated it when I told her I had bought her a trolley bus as a Christmas present.
Lower over all height being lower than MRAP axles would be one advantage to going with Unimog Axles. Otherwise though.... with the average Ambo design... it will be hard to break 12.5'. am putting an Ambo Box on a US military truck and don't think I'll break much over 11'
