hello fellow texan, (el paso :$)
im sure you know all the basics such as make sure they have a spot out of the sun, no one wants a roasted chameleon,
that they have plenty of foliage to keep them happy, a cage serves two purposes, to keep your creature in, and things you dont want in, out.
in dallas weather id say a place on a covered porch, or some other shelter from extreme wind and sun would be a good option.
might want to look into creating a mister to give him a place to cool off if the heat does get to him. using pvc and some mist heads along with a basic sprinkler system, can be found at lowes, homedepot etc. a weekend DIY but i believe it would be cheaper than buying a mist king of comparable size
just throwin out ideas

last link takes a bit to load, and id sugest dipping the ends of the cut pieces in the wood sealer, good wood working practice and all, longjevity of your build etc etc etc.
please share with what you decide on and provide pics, i did a diy indoor cage made out of aluminum window screen materials... its a so so job
