I think the travel cot is an excellant idea for camping to keep her off the dirt and give he a comfortable place to lie on our hot summer deck. After setting it up I found my dog doesn't like it because the tarp isn't taunt enough.  The tarp has a sag which causes my dog to hesitate jumping on it.  When she jumps on it her feet seem to feel unsteady so she jumps right off. 
There isn't a way to adjust the tauntness.  I have never seen this one in person but other that aen't portable don't have any give.
 I will keep it for a week to see if we can get her feeling secure on it.  Will keep you updated.
