The standard tent for years in Alaska has been the Cabelas Alaskan Guide model. The 6 man model is perfect for two people using cots. It weighs about 30 pounds, is completely water and bug proof, and will stand up to high winds.
A wall tent is a terrible idea if the bugs are out, as they almost always are on early season hunts. You will go crazy if they are after you in your sleep - the day can be bad enough. Also, you must expect to be wet, constantly. A Canvas wall tent is the wrong way to go.
If you want true luxury, the Cabelas 8 man tent is big enough for three cots and gear, and is about 7 feet tall inside. Quite a nice setup and only about 40 pounds, give or take.
