Awesome! I hope you get him/her. My setup is only 6 months old. I collected the branches from trees in my back yard. Put a couple of these fans on top to suck the air out during the day.

Your chameleon will love the larger enclosure. Did you get the version with screen window on the side walls? I also have 2 fans on the top screen running during the day to help with ventilation.
Here is my setup
I setup an automatic water dripping system for all my chameleon enclsoures. Bought the parts from amazon and home depot. Plug the pump into a smart plug so I can schedule the time and duration for the system to run each day. It is working great. Speed of the drip can be adjusted as needed...
This is what I use in each of my enclosure. No complaints so far.
