If it's a side vent, even if the upper vent is louvered metal, you can remove it and the lower access vent panel and access the insulation.

The upper side vent on my TC is louvered metal, attached with 12 screws (square drive typical RV screws) and sealed with Butyl tabe. I removed it and the lower plastic access panel and that allowed me to stuff a bunch of extra insulation into the space between the fridge body and the outer cabinet and install a curved aluminum (I used a piece of aluminum flashing from Lowes) to fabricate a curver upper baffle to channel the air out the upper vent...smoothly. When I replaced the upper metal vent, I removed the old Butyl tape and applied new tape and screwed it back on.

Stuffing in the extra insulation (unfaced R12 glass wool), I used a wooden yardstick to jam in the insulation. I managed to get in about 1/2 roll, the more, the better. RV builders really skimp on insulation around the fridge. Never could figure than, insulation is dirt cheap.

I'll see if I can add some more insulation. I recently had to take the fridge out to replace the thermocouple, and it had a tiny little square at the top of the unit.

It's a side vent fridge and I have plastic removable upper and lower vents. When I remove access panels I see all the components there (condenser, tubes, etc). There is a tiny bit of glass insulation on top of fridge between it and the countertop. Also on the sides between fridge and cabinet sides.

There is also baffling along wall (between two access panels). I'm trying to picture where the insulation was stuffed. Do you put it between the "pipes" and fridge, between pipes and wall or just all over? I assume I just need to keep away from burner tube.

When I get back from the trip I'll fashion the top curved baffle that is missing now. Just wanted to clarify on the insulation.

Thanks
