The cobb is a nono inside a car. Inside a tent there is plenty of ventilatoin (but still too little for my comfort and a Cobb).
Go look for an eberspächer or webasto.
There are 2 kinds, 1 one that warms the engine via the coolant flow, and one that blows hot air into the car.
You would need the second type, cabin-heater. E.g read about it here: http://www.type2.com/bartnik/ba6art.htm
Quite often you can find the Eberspächer cabin heaters for less than 120£ on ebay.
Take care
