GeaffA, really like your "stone stomper" , how does it attach to your vehicle? Can you access the rear of the vehicle whilst it is place or is it quick & easy to disconnect?
Queenkat, I have a Kaymar rear bar with dual rear wheel carriers. It provides the connection points.
The guard has bungee chords with plastic end hooks (ebay) that loop around the connection points on the rear bar.
If you don't have a similar rear bar, you'd need to provide something across the rear of your car to attach the guard to.
I drop one corner of the guard if I need to get into the back of the car. Very quick and easy.
