nice kennels from what i have seen. would love to have one, but when im done with school im probably going to get a gunner kennel. i like the lock feature, and their demo videos show them to be insanely tough
tough is one thing but the summer in the south is a diff thing. yes they may be "insulated" but the door looks very difficult to put a fan on and there is not a huge amount of ventilation on the box. soon as the dog gets back in the kennel after training that box is going to heat up extremely quick.
with a cover for the winter and fan for the summer the ruff tough is a safer option in my opinion for the dog. is the ruff tough the most secure kennel no but anyone that wants to take something will find a way to do it.
