I did the same thing, not knowing what I was doing, just made obvious sense to do it since air cold air was being sucked right back into the AC and not forced out into the living space. I used aluminum stove pipe tape (extremely sticky and meant to be used on gas water heater or gas furnace flue pipes). So the tape will never be a problem. Once all the holes were plugged, BIG, BIG change in air output!
Good tip here! Easy fix and costs nothing but some tape.

I recently saw a ytube vid on cutting out the plastic "grill" on the fan output side of the condenser and replacing it with metal lath to improve air flow and thus improving the efficiency of the air conditioner. Has anyone tried this? And did you notice any difference?

AC is my business
Yes, increasing air flow across the coil will reduce head pressure, thus reduce suction pressure making the air colder, to a point. I'd like to see accurate before/after air flow readings, not "modeled" with a little 12 volt fan. CFM and static pressure (that's the pressure loss across the louvers he's reducing) are not a linear relationship. The proof really is in the reduction of head pressure and there is no before/after reading.
I found a big installation error on my last rig and this reminds me to check this one. When they installed the ducted conversion on my last one they did not seal the supply and return plenums properly, meaning a lot of air was just short cycling between supply and return, not getting to the space. Took some foil tape and sealed between the two plenums and it helped A LOT!

My bad! Here is the link https://www.youtube.com/watch?v=aWUqQnEw-8Y. Hope this gets you there. I live in extreme heat although I rarely RV in it! I just thought if any one else had tried it they could offer a second opinion. It technically makes sense but does it really make much of a difference was my question.
