The RTTs look cool, the tent on the second story with ladders running up look as if they are keeping the lions and bears out of your tent.
When I was in the Army, I used a hammock and stayed in trees several feet in the air tied off to other limbs. Then, I didn't have those midnight trips. I jumped out of bed. Now, I can't really imagine having to turn around and head down a ladder, especially half asleep. Seems you really shouldn't have a few beers in your tent either. And where I have seen pics with some small kids in the tent, seems like being out in the bush and having a small child fall breaking an arm is not a very good plan.
So, the question is, why aren't the tents on a lower level with racks to store gear above. Or in containers that could be set outside, that would make a table or swing out for the kitchen, etc. Travel with the gear low keeping the CG low and toss it above to set up camp and pitch the tent so you can step in from the ground?
I can see where such a set up would make one more vulnerable to lion and bear attacks, but seems it would be safer considering other risks.
