I'd like to talk about tow-dollies. Thinking that I might want to turn my M353 trailer into a tow-dolly, like Canislupus suggested. I searched for 'tow dolly' and 'tow dollies' but I'm not finding much of anything. Anybody care to share pics or info about converting an M353 trailer into a tow-dolly? Any input regarding tow-dollies in general is also welcome. I don't have a 5th-wheel trailer yet, but would like to buy something that I can haul 40ft shipping containers on (behind my M109).
