The 6800 does indeed have a lot of space, but pulling around in the ice with any sort of snow can be a bit tough. The new pop-up style Clam's are a great choice if you're looking to house several people and still stay somewhat mobile. You can throw any size (Hub, Base Camp or Command Post) in the backseat of a car and away you go. You can also lay one in a sled and toss the rest of your gear in there and have no problems pulling it around through the snow.
I've taken a Command Post with me on guide trips and have just thrown it inside the tub of my Thermal X and onto the lake we went. Had enough gear (along with the Command Post) loaded in the sled of the Thermal to adequately house an eight-person guide trip... tough to beat when looking to add more people and keep everyone comfortable...
The pop-up style Clam's have created an inexpensive option that offers a lot...
