The Integral Designs version on the Bibler Eldorado only with better fabric. ID used Event fabric in their single wall tents which breaths better. I modified it by having a cook hole sewn into the floor to allow cooking during storms. It also greatly facilitates sweeping out the snow that inevitably gets brought inside with you. Buyer pays shipping and transaction fees if any. Please text @7757901704 as I don't check in here often. Thanks.
