Isotherm Fridge warms, not cold all time? - Tab 400 2024

I did a bit of searching and got a few ideas but thought to create a post to see if I am missing an easier fix on our fridge or its something I am not doing right.  Our Isotherm 130 in the Tab 400 2024 at times we will loose the fridge temp (get near 50 deg F).  To improve the issue I installed a fan inside the fridge, a wireless thermometer to monitor, turned dial all way up, and tried to keep door stacked with cold drinks but we still lost it again few weeks back.  Also made sure the door is not in vent so it doesn't come open while driving.  I notice the issue more when we get the sun on the driver side of the camper either when driving down road or at campsite on shore power.  I am thinking to put a small fan at the top back of cabinet to assist with moving air off that back wall behind fridge to the front grill over fridge.  Found an usb fan and temp controller on amazon for 16 dollars and reading online seems that 25 CFM is all I need to assist with the intended design of airflow and not short circuit the airflow.  Also will keep a small fan inside fridge to keep air moving.  Anyone already make a similar change and if it helped?

Anything obvious I am missing?  I expected this fridge to keep up better but maybe they just don't have the power.

Try removing the freezer drip tray when using the fridge . Make a world of difference . Just make sure you re-install it when the fridge is turned back off and emptied or the fridge compartment with get "rained on" when the freezer thaws . This trick worked wonders in keeping the Isotherm "cold" in or 2024 400 . 

I think NuCamp needs  to put a vent / fan to the outside in that Isotherm compartment to relieve the heat build up . The fridge does transfer a lot of heat to the cabin when it's hot out . That said , the drip tray removal trick really does help. 

I also "pinned" the door closed while traveling . A few times I noticed that the door would crack open into the vent mode when traveling , especially when the door was loaded up with drinks.
