I'm thinking about building myself a new dog house

The truck I recently purchased has a scissor style hoist. The cylinder is leaking badly, and I'd like to reduce the overall height by removing the scissor hoist and subframe assembly and using a telescopic headboard mounted lift cylinder. This will mean moving the hinge points to the truck frame, and building a crossmember for the base end of the cylinder, and modifying the headboard (which needs repairs anyway) for top end of the cylinder.

Has anyone done this before? Any pictures of the detail of how a dog house is typically constructed, and how the base end mount is usually built?

Moto, I've seen your pictures of your work on dump bodies, so maybe you have some input on the headboard construction?
