Took my trailer to La Mesa t.v. in tucson for warranty repairs.Dometic Freezer was fluctuating between 5 and 25 degrees ,25 degrees equals runny ice cream, I was told that the manufacture said " anything below 35 degrees is freezing and fluctuation is normal" somebody needs to take a science class cause 32 degrees is freezing! We camped at 7000 ft elevation for a week 20 degrees and the furnace wouldn't work,we froze. Domestic told la mesa t.v. that the FURNACE is not made to operate above 4000 ft elevation. Did forest river put cheap appliances in this trailer?
