...A suggestion to anyone doing a large setup for the first time - Arrange it so that you can walk around the entire habitat should you need to for whatever reason...
Agree 100%; large heavy set-ups should be reachable from all sides. I know of a couple huge aquariums whose owners had to either empty them or demolish a back wall when things went wrong .
Remember to take care of the enclosure and it will take care of your frog !
