OP, keep in mind that ALL absorption fridges struggle to maintain interior temps when ambient rises above 90 degrees. Out here in the desert people use various crutches, first park with fridge side in the shade, add fan(s) in the compartment (bottom pusher, top sucker or both), install a sunshade over fridge area when parked and some even use a box fan blowing into the compartment.
Personally I ditched the absorption type fridge when we went from Class A to Truck Camper and now park where ever I want and our compressor fridge keeps things properly cooled no matter what ambient temps are as it runs off solar charged batteries.
