I had an identical one, different brand but they all come out of the same PRC factory...
Easy and quick setup, really comfy mattress, best nights sleep I ever had and that includes at home!
The worst bit was that the zip up cover had a limited life, but mine was s/h. Sold it on and new owner had a fresh cover made up.
If you have a pickup they are highly recommended, bit of an air brake when on top of a tintop so I would recommend some sort of front faring to help your mpg.
