this is our second ramp---the first one was ran over with our Gator ( live in the country ) but still withstood this insult and was easily repaired but i had already ordered a new one and decided to kept them both  because i love this ramp --makes it so easy for my boy  ( Big Rotti ) to get in and out of our truck , car ,gator with ease thus saving his joints ( not jumping ) --i have had other ramps before which were not as sturdy for big dogs --thank you for this wonderful ramp
