Darn, could have just edited the other one... double post -_-
Um... so yeah, a second uth would be awesome. Get on it. You'll have the problems solved all around.
With reptiles my motto is: The less I have to do to keep their enclosure where it needs to be, the better. If I have to do nothing but add food every now and then and clean the water dish, the setup is perfect. For my Savannah, that's exactly where it is. For my BPs I need to swap their bedding and clean their tubs every now and then in the addition to the above, which is about the best I can hope for.
