At best, I've seen 43º F differential. But that was at ambient temps
lower than 90º F and with a fridge full of cold stuff.

As Richard and others have referred to, the "city water" fan upgrade
likely made the most
positive difference in fridge performance on each Dometic I'd been running.
If you look at the fridge side of other RV's with absorption fridges,
you'll see a large grill
or two. Parking in shade, shady side to fridge, small internal fridge
fan, better insulation,
fridge "management" etc. etc. all help. For point of reference, and
though highly unscientific, 3PM sun at side of Westy, no insulation:
130º F at sheet metal behind fridge. With insulation, 88º F. That
insulation would obviously heat up over time though.

I think too that the age of the fridge, and use (or abuse) its' seen,
play a large factor in
how well if performs.

All that said, even the TruckFridge will be challenged in really hot weather.
For enjoyably cold beer, my TF49 has to be set at around 5 in hot weather.
