UPDATE: Status Unknown. Was on eBay.
(02/15/2013) This trailer setup looks good.
“Up for sale is my M416 military trailer that has been modified into a off-road camping/adventure trailer. This started off as a ¼ ton M416 surplus trailer. It was completely stripped down and sandblasted. The Axle was replaced with a 3500 lb unit with 6 lug bolt pattern for Toyota and Chevrolet. The frame was extended in the front for a cooler rack, and two military style gas can mounts ( gas cans will not be included). Trailer still maintains the military pintle hitch. Body had the floor cut out and replaced with heavier steel. A custom lid was made which opens using a modified tailgate latch and heavy duty lift struts. On top of the trailer sits a large Serengeti Rooftop tent.(http://campinglab.com/serengeti01.html)
