I made my own but have a friend who bought some Rhino Ramps and had them fail on him. He's a retired mechanic and used them/drove up on them correctly, not off-centered which can cause failures. Needless to say I ended up building him a set as well. Look on Amazon and Google for a plethora of failed pictures and you will think twice about the Rhino Ramps (new design is supposed to be even weaker). If you want to buy an affordable safe pair, Northern Tool has a set made in Canada for about the same price with no reports of failures.
