I can send some pics of mine,,,,,,, but not for 2 weeks. Its still at the other place and I wont be there for a couple weeks. It's steel (easier to weld for me), fits a short box, has a 2 piece ramp, and sliding sides, headache rack, winch, and a swing out mount for a winch for my truck.
Highly recommend not making a ramp out of steel,,, very heavy and cumbersome when you have to do it yourself,, especially if you have a herniated disc in your back... aluminum for the ramp for sure. In fact aluminum for the whole thing if the welding works for you and the higher cost of materials.
If you dont get any pics from anyone else, aside from just looking at any decks out there really, I can take a bunch of pics and some measurements if you want.
