AC not blowing good air flow

[Avalanche 375rd]

Hello,

I have a 2021 Avalanche 375rd and I am having issues with both of my AC units not blowing air the same out of all the vents. I have two return air vents for each AC and they do not seem to be not pulling much air flow back into the AC. I have had this camper for a year and this is the first time I have had it out.

Lots and lots of conversations on improving cooling in an RV on the forum. You can do a search to find them but here is a link to a current thread about cooling in an Alpine;
