To steer a bit away from the whole propane-while-towing issue, I have an observation and a question.
Dometic stated that 12VDC operation of the 3-way fridge
in our Casita
would produce a lower wattage than operation on 120VAC or LPG, resulting in less effective cooling; the fridge
should be initially operated on 120VAC or propane
to effectively cool it down before towing it and operating on 12VDC.
My question is what have folks observed when operating on 12VDC while towing in hot weather conditions? Was this satisfactory in terms of keeping things cool?
