I agree a smaller rig for the rental. With just two you don't need all that space. Unless of course you are used to driving bigger vehicles. I would tend to say take more like 5 days. Head up to the mountains. Or maybe the Black Hills where you can see some cool stuff us flat lander's don't have! Or rent it for a extra night and camp out at home just to learn how to play with all the gadgets. Also remember the rig needs to be kept reasonably level to keep the fridge working properly. That way you can get the fridge loaded. Find all the things you forget etc. JMHO Also remember that isn't your sticks and bricks plumbing system. You don't leave the faucet running or take super long showers. Unless of course you have full hook ups. You can find all that out at home in your driveway:)
