Here are the legs, one folded up, the other expanded.
The top and bottom with slots for the legs to slide in,the two small pieces of wood are the steps, which fit in brackets on the legs. The two metal pipes are diagonal supports that attach to the legs when the dropin is setup.
The ramp for the drop in folds in half, and has two wooded supports which bolt to it when you are ready to use it.
This all fits in the back of my 2 door ford escort, when i fold the back seat down
