Not going to lie, seeing a picture of that T100 is REALLY tempting knowing Ive got a Burm that will use every inch of it in the future.....get them to install a big old basking shelf that he would use. Approaching the heating on that bad boy?.....Hmmmm I would guess heating the room is maybe the best bet along with a rhp over the basking shelf?....that's a LOT of vertical space!....I would think too much for a single rhp.
However....it says its 8x4x4....it doesnt look four feet deep to me but maybe that's a typo.
