This is a tough call and I know the guy was trying to improve things, but he made them worse.
This is mt aux fridge fan install as documented in this thread.

It was doing pretty good, but I wanted and expert opinion, so I dropped by the Dometic OEM booth and they said he would have the guys check it out. One said the baffle needed to be cut back a little for better airflow out of the top vent. Said he would be by later to do the job. I forgot to check before leaving the rally. On the way to Georgia I found the fridge temps had jumped 6 degrees (50+), so I tried upping the setting to max - no help.
At the Atlanta campground I got my ladder out and checked.
OMG!
He had cut the baffle totally away. This is totally wrong and does not even come close to what I thought he was going to do which was trim it by and inch or so to allow air flow out of the second row on the vent. It does not even match Dometic's instruction for fridge install in a slid either. As a temp fix to get to Georgia I used duct tape to partially rebuild it. Douing that helped get things closer to the 45 upper limit. I usually shoot for 39. Note the silver foil is the back of the fridge
Finally in Statesboro Ga I went to Lowe's and got some copper plated aluminum sheet metal that I thought I could cut with the tools I have. It was actually easy to work with. I was able to score heavily with a utility knife and fatigue bend a couple of times to break off what I needed
This is what I came up with. I bent the curve using the slots between boards on the table. When finally installed the top bend was flattened. It is slightly wider than the opening so I could wedge it in front of the existing baffel - what was left of it.
Note that it extends higher than the stock one that ended just below to cooling fins. This one extends 75% up on the fins. Fridge temps immediately started dropping and within an hour I was back to the normal range of 40 degrees at setting 3 rather than 48 degrees at setting 5 max. Outside temps above 95 degrees.
After installing I could feel air coming through all three slots on the vent. When I get home I need to tweak the fit a bit. or find a bit stiffer material to use. Its currently held in place with 4 screws and duct tape
I would somehow like to get back to Dometic and let the technician know while I appreciated him checking the fridge out (he did full inspection , check the control board and wiring and inside where the temp probe was - all good), but his trimming was a disaster. Any thought on how to do this?
So when the question comes up about trimming the factory baffle, don't. It's set that high for a reason.
