We also found that this refrigerator was not sold or supported by Dometic in the USA. It is supported by dealers in Canada. We did this research over a year ago so we are not sure about current Dometic policies. If you cannot find manuals on European marine websites let me know and I'll look back and see if I can locate the websites.
It apparently is a very sophisticated refrigerator. My friend was having difficulty with automatic power source switching which was leaving coach batteries dead. It was resolved by cleaning connectors. The refrigerator has a connection which tells it when the alternator is producing power.
Hopefully this helps. If it does not, let me know.

The instructions I found on the Dometic Australian site suggest that you not run the fridge on 12 volt except when the chassis engine is running. If run off the house batteries, it will drain them in about an hour. Still a good thing - you can run it off battery while traveling and be able to turn off the propane. In addition, with the generator, you would still have refrigeration if you run out of propane and don't have shore power. Definitely more options than with a 2-way fridge.
When we got our first RV, we didn't think about the propane burner firing once the batteries got low. Should have known that - just like the propane stove top
The fridge alarm went off in the middle of the night (we were boondocking). It was the last day of our trip and, fortunately, we had several ice packs in the freezer. The fridge temp didn't drop below 45 deg before we were on the road and able to start the fridge when the pu charged the batteries back up to the level needed to fire the propane.
RE the warranty, I would assume LTV would cover the fridge under the 2 year RV warranty.
From what you say, I'm going to assume the fridge used by LTV is auto switching.
Thanks; you've been very helpful.
