You should be concerned with those temps. The fix is adding fans to move more air through the upper outside fins and out the upper vent. It has been documented here by many of us. Ours went from being set on 5 (coldest) and varying temps up to 50 to being set on 3 with steady temps in the mid 30's.

Nearly all RV fridge problems are the result of poor installation by the RV manufacturers. They simply do not adhere to clearance and baffling to move
air across those outside fins and out the upper vent.
