Actually I always use a floorjack and then jackstands, I have a set of metal ramps but have never used them. I'm sure the plastic ramps are fine. I would assume that in order to use a form of plasic for the ramps they must of used a composite that was very brittle(dense) for strength, so if they were to fail it would be immediate where as the metal ones usually slowly start to bend giving you time to crawl out from under your truck before you become a refridgerator magnet. But then again I'm just talking outa my a$$.
