They look a lot better than some of the previous trailers of that class that were released from Quebec. They usually have fist sized holes through the metal from all the rust.
The trailers listed are the M-104s. They are not overly desirable. It is quite a heavy trailer, with an air actuated hydraulic braking system. To use them you have to have an airbrake endorsement on your license, whereas with the truck that would normally pull them (the M35 Cdn) they are hydraulic with air assist, so no license is needed.
To put that trailer behind something like a 1/2 ton, you are just asking for an accident. I have one myself which I converted over to a smaller axle which I use to haul wood from the nearby forest to my house. They are heavy enough to withstand a lot of abuse.
