We also had a 3 way Dometic in our LTV Free Spirit LSS.   Wish our PC had one.

Smart money says not to run the Fridge on 12VDC. Either AC or Propane, which won't kill the charging system/ignition of the engine on the road (which has happened to me more than once).

12 volts is as low as you should ever discharge your batteries to prolong the life. It's less than 50% charged.
See chart below. Read your battery voltage with your inverter voltage display or with a digital voltmeter.

Percentage    
Charge   Voltage
100          12.73
90          12.62
80          12.5
70          12.37
60          12.24
50          12.1
40          11.96
30          11.81
20          11.66
10          11.51

To run a frig on DC takes too much power and batteries would quickly be discharged. That is why they eliminated the DC 3-way option.

There is absolutely no reason to turn off your refrigerator while traveling. That's what it was designed to do.

I have the three-way refrigerator and always run the refrig on DC while driving.  The engine seems to keep the battery charge up just fine. In my previous class A, I ran the larger two-way refrig on Battery power thru the inverter while driving and never had problems with that either.  I have no objection to running a refrig on propane while driving but I don't see why I would prefer that if my batteries are handling the job.

I suspect we are all prejudiced by our personal experiences regarding most things.  Me?  I have always preferred to go down the road on DC and have done so for most of my 30+ years of owning motor homes.  Our unit prior to owning our PC, we got over six years service on our set of coach batteries and always ran down the merry lanes on DC.  I replaced the coach battery after six years just because it was original and figured it was time.   The coach and chassis were never taken back to any dealer for service or problems after I drove it off the sales lot after buying it new.   So, I would conclude that for me the DC worked just fine.  Plus, on propane you always have to remember to turn of the refrig when gassing up.   Boom is a bad word.
