Sort of an accessory I guess. We finally had a reason to put the dogs in the OB last week and both of them were skittish about jumping in. Plus they are getting old anyway, this was coming. Anyone use a ramp? None of the ramps I've found online really separate themselves as "good". Ideally the thing would fit in the car somewhere since it would come with us on trips. Amazon has this tri-fold ramp, but reviews are mixed. I don't necessarily need cheap. "Good" is better than cheap.
These are a few I am looking at. I originally posted a tri-fold, but these seem better and not much larger folded than the tri-fold.
