Well your Indiana 6 is about as close to a Bear Lake 6 as you will get for the carpet but sadly the footprint for the BL6 will be too wide as the BL6 is 420 wide and the Indiana is only 400. You could trim down a BL6 footprint or just buy a large builders tarp and make your own. Just remember that the footprint must be slightly smaller than the groundsheet of the tent to stop water building up under the tent.
