I am very seriously considering making a trailer based on M105A2 bed. See this page for M105A2 trailer
ADJT INSIDE WIDTH 74.000 INCHES NOMINAL ADJU INSIDE LENGTH 110.000 INCHES NOMINAL AFMQ INSIDE HEIGHT 18.000 INCHES NOMINAL
Basically I decided to do it, unless someone talks me out of it. I have a chance to get that bed.
M105A2 is a military trailer. It is unacceptable for civilians with pickups for a lot of reasons such as being too tall, sitting too high, having a incompatible lighting and braking system, etc.
What is being sold near me is a M105A2 bed only. Someone is also selling a 3,500# axle.
So, what I think I can do it, buy the bed, the axle, buy a tongue (I already have lights, IIRC), trailer jack with wheel, and weld it all together. Since my axle would sit a lot closer to trailer, and have a lot smaller wheels, the trailer would not be as tall. Also I would have a braking system if I buy a tongue with brake cylinder.
I expect the total cost of this, not counting time, to be about $500.
I may also install a winch on this thing.
Also, how much would it cost to hire a sandblasting company to blast it and paint in grey color.i
