Pipe elbow can only be used at stove to redirect direction of pipe
Water can collect on the roof in an "eave trough" which is a low area just before the sidewall created by a not tight roof or loose fly
Fly overhangs 1 foot past each side wall to take snow and water from tent walls reducing the possibility of water coming into your tent
The right side flap has the 10" storm flap which overlaps the front left door flap
I am very pleased with this purchase
