My 78 Royale had a Dometic 3 way unit that was manufactured in Europe. It
had strictly manual controls, (no circuit boards) You had to light the
propane by pushing on the prime knob and pushing the manual spark lighter.
The electrical stuff consisted of 2 different heating elements, one 120
volt, one 12 volt. The 12 volt one was smaller than the 120 volt one, and
was intended to maintain temperature, not to cool a box that was not
already cold. Eventually, the rust devils got to the entire unit, and it
looked bad. I bought a new dometic that was a 2 way unit, and fitted the
old door graphics to the new unit. Now the new unit looks old again. The
new dometic has circuit boards, and requires 12 volts to even run on
propane. I do not look upon that as a feature on the + side of the ledger.
But, the new one is made in USA out of foreign sourced parts. Unknown to me
if that is good or bad.
But, I have had bad luck with Norcold fridges when mounted in GMC's.
And the vendor in Texas would not stand behind the warranty. So, choose
your vendor wisely, grasshopper.
