Does anyone have one of these? My dog is getting older, and I forgot about the height of the xterra and it would be difficult for him to get up in the car with ease.
I looked at some different solutions, and this one looked pretty practical, as for the dog, plus it holds 500lbs and it is a supplemental support for a human to sit on, or stand on to get up to the roof rack.
I know it lowers the clearance a bit, but I will not be doing any serious off roading, so that should not make a big difference.
Any opinions on this gadget?

Much regards Flatfoot
