Hi Gorila,
Sorry to say I don't have any pics of my old rig. Come to think of it, I haven't seen it running around here lately. Anyway, the top speed for my M813 was 60 +/- and ran the original Cummins NHC 250 w/ 5speed od. Ran best at 50 +/- and milage was 6-8 mpg, glad it wasn't choosy what kind of sludge I fed it to run on; mostly waste motor/hyd oil. Try to google "Charlie's Truck". He did a great looking job and used a 2 1/2 ton. That should give some food for thought.
