Well made, sturdy, not too heavy.
Easily accommodates my 130lb and 110lb dogs.
Fits nicely on the seat through the back door of my Colorado Crew Cab and still has a gentle slope.
I place a tool box under the top corner lip to prevent wobble.
Trained the dogs inside by luring them across it with treats and praise.  Successful on the third atttemp up and into the truck no hesitation exiting the vehicle.
A superb product, well worth the money, and it should last for many years.
