too big a cage?

[Creep]

so josh finally contacted me back after i told him all the temps, size, etc. of the tank that i'd mentioned in the other thread in regards to the skin and bone monitor he sent me... he's saying a 6ft tall, 6ft long, and 4ft wide is too big for a peach throat monitor nearly 2ft in size and i need in a much smaller enclosure with a few hides and a water dish... don't mean to be rude but i kinda think that's bull... since peachies do climb, any monitor needs a "dish", if you can call it that, large enough to entirely soak itself, etc.

what do you all think? he claims it was eating like a monster, quote "pounding" down pinkies, crickets, and superworms, but when it arrives, and a couple days after, it takes no interest at all. haven't seen any poop either.

edit: for the basking stack in the last thread, it's moved out from the cool side to basking up at the top of the stack. also, it is flicking its tongue a lot and will zip off at a moment's notice, so it's not like it's not lively..
though it will just sit on your hand like there's no care in the world(had to make some adjustments and had to move it)... the first day it sat there and wouldn't flee for nothing, now it will run off if it feels like it, so maybe it has eaten some crickets that was in the enclosure. what do you all think?
