Replace 13500 Coleman with 15K Air Commander
We are having trouble staying cool in our 31" TT with a large slide in FL. Adding a second AC would be possible but with the labor to get power to it and the obstacles on the ceiling around the front...

The difference in cooling capacity will be negligible...maybe 1degF. I suspect you're having problems getting below 80F inside. Atwood HVAC is now owned by Dometic and they are having A/C issues of their own using the current freon spec.
Due to rear A/C problems last Summer in TX, I used a portable self contained A/C and directed the exhaust vent thru a window...wasn't pretty, but it dropped the inside to mid 70's.
The price of the Atwood unit sounds good and I too am a fan of Atwood products, but I would go to a Heartland Service Center for the installation. Your TT is new enough to ask if the Coleman A/C is working to spec. It's frustrating to discover comfort issues while there's better things to do, but heat will beat cooling BTU's when there's too much.
