I have one, but have never used it on our 310RL. It just seems like another thing to pack and carry, so even though it came free with a previous 5th wheel, I have never given it a try. I have read a lot about the 5th wheel tripod, but it seems like half the people who use them like them, and half the people think they are a waste of time. If you are near SE Ohio, I have one I will sell you at a bargain price.
