I really liked this pet ramp.  I have an Xterra which is a hefty jump up and down for a dog from the back of the vehicle.  Especially a dog with hip issues.  I bought this ramp and with a few simple tries my dog got the hang of it and loves using it.  She is so much more comfortable walking up or down the ramp versus trying to jump up into the vehicle or jump down onto hard concrete.  It's a little bulky but it's not really heavy and it's well made.  I would recommend this ramp to anyone.
