I bought a pair of hammered ones for $250. Straightened them back out with a ginpole and a 5 lb sledge More typical price for nice usable and complete is b/t 4-600. Drunk people ask more, get less. I belong to the military vehicle Preservations Assoc, and get monthly classifieds, so I think I'm pretty current on pricing, but ymmv...
Looked for one for years around here. Anything that is not beat to hell, gets at least 700.00, and good ones are way more. I picked one up two years ago finally, wanted to use it as a mexican blue print. I have pulled a borrowed one off road behind the red truck for years, and they go anywhere, and work very well, set up with the pintle/lunette ring.
I looked her too for a long time before i found one. i think mine is a 410 or something similar to the 416 with out the shocks. i t had been converted to a standard ball hitch. I paid $375 for mine and had to replace a third of the bed, tires and wheels and painted it. i couldn't find anything in any better shape for much less than $1K. I love my trailer and use it quite a bit. I keep all of my camping gear stowed in it and it is ready to roll at a moments notice. Ive towed it behind my M38A1, my FJ40, my 4runner and my F250. nice and lightweight even fully loaded with my camping gear. I don't think you would go wrong buying 2 for $400, you should easily get your money back if you were to sell just one of em. Wally, Denver, CO.
I bought a Canadian M101 from Whiteowl last winter. It is in great shape and was as advertised (like new). I pulled a wheel to repack the bearings before my first long trip and the grease looked new. I repacked it anyway but didn't pull the other tire.
