My two SD retics are getting to the age I have a good idea what size they will end up. So now is the time to start shopping for their final enclosure. The male is 3yo and right at 5'. The female is 2yo and just under 6'.

I'm vending a show this coming weekend and had planned to talk to another vendor about doing 2 custom 6'lx2'wx3'h enclosures. That other vendor canceled so looks like I'm stuck with possibly ordering from animal plastics. I have no limit on length or width but do have a bulkhead just above 6' so the total height can't be above that. I wanted the 6' length so they could stretch out on the floor and the 3' height for many arboreal options. These will be in my reptile room which is kept 75-80 ambient. They will also have rhp's.

Which would you choose? Or any other manufacturer options with length and height?

1. A20-48x24x36
