I believe that AP offers the option to have the RHP installed in the center of the T8, so that half would be on each side of the divider, so that is definitely an option. As for acrylic vs glass doors, I would suggest glass. Granted, acrylic is a bit more efficient in the insulation department, but it scratches a LOT more easily. Since you're wanting to have a better view of your boys, that's a big plus for glass. That being the case, I would consider having your ventilation along the back and/or sides of the T8, putting an RHP in the rear center, and keeping the top solid to help maintain temps and humidity. Also, considering the terrible loss you had to deal with before, I STRONGLY recommend the VE-200. It's not cheap, but I think it's well worth the money to know your animals are safe. Another thing worth mentioning is the drastic humidity change in the mid-south from season to season. I grew up about 200 miles north of you, in Memphis, and I still have nightmares about it! Late spring through early fall, your humidity is pretty impressive, but having the heat on during the winter sucks every last drop of moisture out of the air. If you've got central heat, it makes it worse. If at all possible, get a humidifier for the room that your snakes are in.
