I bought my tub from Murdochs farm supply and then ordered the tent kit from throne brothers in Minnesota. I bought the medium cabin and love it. they are very well made= heavy =snowmobile to pull it! buy the hyfax kit , it real helps save the tub on the rocks..
no place - as of last ice season. i bought the sled at gander mountain, then looked at the tent/shack part but could only buy online.
i ended up getting an eskimo flip sport at sportsman's warehouse (single person model) $179.99 and i really like it! so now i have the otter sled for mild short trip days and the shanty for more serious situations.
