My Work and Play ramp developed a crack in fiberglass and felt soft just above hinge where motorcycle wheels passed over. Door was replaced under warranty.
Although I was well within the weight limit, all the weight of the motorcycle was concentrated in a very small area over the hinge. I had a 2 ft by 2 ft, 1/4 inch diamond plate with a small lip made to spread the weight as I drive in. I don't know what the ramp cost but I can't imagine it was too cheap.
