Subject:insulating hot side of Dometic refer

It's time for the periodic fridge removal and as usual I'm wondering
what  could be done to improve it's hot weather performance.  Mine
seems to work best on electric in hot weather.  I theorize that the
propane fire puts a lot of extra heat back there, making it harder
for the refrigeration process to expel heat.  So maybe making sure
more of that heat stays away from the fins would help.  And also
keeping more heat away from the refrigerated box seems like a good
idea.  Would it help to put some thin insulation like reflectix
between the heat radiating fins and the back of the unit?  It seems
to be made as one unit with the fins attached to the back in several
places, so doing this would require a number of separate pieces but
not too hard.  How about adding insulation around the "hot column"
and on the exposed exhaust pipe as it goes up from the column to the
exit outside?  That is just bare metal throwing off heat behind the
cabinet.  Any ideas or comments?

While I'm in there I'm prepping for the classic exhaust fan in the
former city water inlet door which should help, and putting in a  12V
accessory outlet next to the vent grille on the back of the fridge
cabinet.  What is the best choice these days for a heat transfer
compound to put between the cold-pipe and aluminum fins inside the fridge?
