Love the ramp -- it folds right out/in with no sharp edges or anything, the surface has a non-slip surface which my 60# dog manages quite well -- just took a little practice with it at a lower angle then up a little higher each time.  He's getting older now and has trouble with his hindquarters, at times he can't seem to pick up the rear legs, so obviously he can't jump into our Mountaineer anymore.  I'm 67, female, and I can pick it up and put in place -- it's about 18# so not bad... I am very happy with it and am glad I didn't go for the cheaper metal one (from another company) that had comments regarding sharp edges. And this one is long enough, at 6 feet in length it can accommodate the height of the liftgate bumper.
