[/IMG]Cabela's has one i just bough that was 60.00 and it's raised up.not to big but perfect for what your looking for. i needed the same,something to put firewood and cooler maybe chairs on. take a look at the website and i will try and get a picture up of it.
the great thing is it sticks out aways but you can slide it in and drill a hole if you want to have it closer in. it will hold 300 pounds of stuff and when i spoke to the guys at cabeleas they said that they sell a ton of them for suv's and jeeps.
