Other than amp draw, I think the greatest difference you would see between the 11000 and the 9000 would be the time it takes to bring the TC temp down to temp. That might be splitting hairs. The A/C cools the air a little more each time it cycles through the A/C, until it is the temp set on the thermostat control.
I think the 9000 series is a great choice for a TC. I have had mine since 2004, and it has always cooled my TC. In the Dakotas, it was so hot I ran the A/C while I was on the road. It was cool in the TC when I stopped for the night.
The freezing in one area and too hot in another is simply air flow. A simple 12-volt fan (about $15) from Walmart will work great. I have one I sometimes use, to circulate air from the A/C or hearer. They have a very low amp draw, and plug into a cigarette receptacle.
