I am searching for the posts and can't locate them right now. But there have been some reports of a piece of the ducting that is not secured in place falling and blocking airflow from some of these units.
I'm not familiar with exactly what is on a pinnacle but I'd assume they are all similar units.
My dual units don't keep up like at home but they definately cool the rig better than what your getting.

Ya'll, please keep us posted, we are one breath away from pulling the plug on a new 36FBTS Pinnacle and there is no way living and also primarily camping in Florida that we can deal with inadequate ac. Thanks all
I have a 2016 FBTS and ya u gotta run both ac units but I can cool mine down. I had a problem with the bedroom unit kicking out compressor. Remove the inside cowling and there is a fiberglass piece that separates the blower from blowing air back into the evap side. Mine was just laying in the cowling. Put back in place and taped real good with ac duct alum tape. Also make sure the temp sensor wire end is against the evap fins. Sometimes the sensor comes loose from the fins. On main unit u have to remove the top cowling and look down inside for the piece that separates the evap from condenser. I have not done that yet but another posted that it is real tight to get to. My bedroom unit would keep kicking off the comp on low fan because of the piece that was loose. It did not kick out in high fan but was not blowing as cool and like Grumpy said also was not blowing the air into the duct system but just a little.
