Our previous TT was a small 17' unit from another manufacturer, and it had the small 5,000 KW (I think) AC unit. Did it do the job down here in Texas - NOPE! The refrigerator was a small under the cabinet model and it also fell short of doing the job down here during the summer.
. We upgraded to our present unit and upgraded the AC to 15 KW - no problems staying cool now.
