Personally, I'd go with a Kodiak Canvas 12x12 cabin tent (comes with a stove jack). Canvas give you the option of the type of heat you want to use (propane or wood stove). The size will meet your needs, and you can always add the awning (it can be enclosed) if you feel you need more room, a cooking area, storage... If you donot want canvas, you could go witha Cabelas outback Lodge (no stove jack), but unless you install a stove jack there is no way to heat it without condensation issues. Both of the above tents come in 10x10 and 12x12, but a 10x10 will leave you wanting more room, considering the size of your family.
