Wall tent equals a truck? If you will be truck camping, throw in a couple extra fleece blankets for insurance against the cold. You can add these to the sleepers as needed. Also, be sure to bring two foam pads to sleep on, per hunter. Air matresses do not afford very much insulation, and they also have a bad way of failing on you... Fleece gloves and a fleece hat to sleep in. Sleep in your thermals, dry thermals not ones you had sweated in.
Speaking of which, I intend to start a thread about proper winter clothing. In a nutshell, if it has cotton in it, leave it at home. And yes, I know, I will hear from a bunch of ol' timers about how they used to (and still do) hunt in their cotton stuff all the time, but I wont. Get lost or injured wearing cotton in cold wet weather, and you die. Get lost in poly, fleece, wool, etc...you have a fighting chance.
