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...

I'm a fan of the Atwood, but it can be a non-trivial swap due to thermostat wiring, which could/would add hundreds to installation costs. Atwood uses their own thermostat cable, the furnace leads hook up to the thermostat for Coleman, but the roof unit for Atwood. For this reason I would upgrade to the larger Coleman instead, unless running new thermostat wires is easy in your layout.
I would also look closely at the ductwork on your unit, making certain it is well sealed, and all of the cooling is getting where it needs to be.
Thanks for the info. Based on your suggestion I just removed the ceiling fixture off the Coleman and a huge amount of air is coming out directly. The entry to the duct system is pretty small. One on each side and is 1.5" x 7". They have a blocker panel inside the ceiling fixture grid. Thinking of putting an opening in that panel. I can always tape it back up.
