My Newmar 3436 Fridge - 120 Vs. Propane

Electric elements and propane flame provide roughly the SAME heating provided both are operating correctly
Propane is a bit quicker at beginning but both work same provided cooling unit functions properly

If cooling unit has any internal obstructions then overall cooling will be affected regardless of heat source

If dry camping/boondocking then best source would be propane vs AC
If on FHU then AC would be better option due to site fee already includes AC
While in transit.....either but AC if running generator for A/C Cooling then AC for fridge

Bingo, The BTU output is identical for LP and 120. BIG OLD wives tale that LP is "better" Than 120. Now, there ARE problems as OLD BIS stated.
1. You are on 120 at a CG that is full and the weather is hot and everybody is running roof AC's. That usually means the 120 LINE voltage will drop and may drop drastically, which will cause the refer to NOT get cold correctly on 120. This is why it is extremely important to have a plug in digital 120 volt meter in the RV to monitor line voltage to the RV. If it drops below 115 volts SWITCH to LP until the line voltage is above 115 volts. Due to this, people think 120 is inferior to LP, but it is the CONDITIONS that are causing the problem.
2. LP pressure is CRITICAL for operation on LP. The LP flame is basically USELESS in the burner flue/chimney. There is a LOT of heat, but it does not do anything. That is why they install a metal Spiral just above the flame to dispurse the heat to the Metal CU tube.
3. To get BEST results on Ice Cream. Purchase the rectangular box type Ice cream and push it against the back wall or the wall where the CU freezer tubes are located. This will yield colder Ice Cream. The operating temp of the Freezer is 0 to 10 degrees. Most residential's will operate in the 0 to -5 degree range. Doug
