Northstar X6
The Northstar X6 is a two-room design that can easily sleep six, with space for gear. The interior is divided into two large rooms, one of which can be converted into a screen porch by rolling up the fabric on the sides. There's a complete rain fly that covers the entire tent and provides two vestibule areas; the vestibules are sheltered from the elements so you can preserve ventilation and provide shelter for people entering the tent when it's raining. The tent boasts a center height of 6 feet 2 inches, and measures 14 by 8 feet on the outer edges. The tent is made of polyester and nylon, with external aluminum poles for support.
Montana 8
The Montana 8 is a modified dome design that adds two side "rooms" onto the center structure for extra room. It's a large tent, with a footprint of 16 by 7 feet and a maximum center height of 6 feet 2 inches. There are screen windows on each end for ventilation, and a removable rain fly that exposes several screen windows at the top. The one entrance has a partially covered vestibule to prevent water from coming in the door. The tent is constructed of nylon and polyester, and is supported by internal fiberglass shock-corded poles.
Weathermaster 10
The Weathermaster 10 is the largest of the tents covered here. It has a footprint of 17 by 9 feet and a ceiling height of 6 feet 9 inches, and can sleep 10, five in each of the two rooms. The Weathermaster is constructed of nylon and polyester and has power cord ports, two entrances, including a hinged door, and ventilation windows at both ends. It's designed for extended stays in areas that may see a fair degree of inclement weather.
