It has happened to some RVs (not just RT) that the fridge was not plugged in from the factory. You would think the QC should have noticed that.
The lights were working though, so I *think* it was powered. Not sure what the issue was but I'll ask the tech when I see him next and post it.

.

I am glad you are standing firm on the acceptance.
Judging by the web posts around the internet, and there are many on various forums, RT has been getting away with murder for too long. One woman who bought a top-of-the-line loaded Sprinter similar to yours. She had so much problem with it, she sold it at a loss after 6 months, because she could not handle the runarounds and excuses.

I hope you have a better outcome.

I expect your fridge is a compressor fridge with no ammonia in it. It should be able to run on either 12v or 120v power and many simply flip the 120 volt breaker and run it on 12v all the time which is more efficient than 120 volt operation.

If you do Facebook, consider joining the Roadtrek & Hymer Owners Group. Lots of owners there willing to share technical info. Open technical discussion allowed so different than the Roadtreking group.

We carry one with use, although we are more critical as our smart regulator runs both alternators and we lose all charging if it fails.

I think the spare is a plug in for a Balmar regulator, but we had to due our own splice in plugs for our Ample power regulator, so we can run either of the alternators depending on if only one is working.

No question, a bailout single stage regulator would get you back to an upright condition, but considering that the cost of his coach is in the neighborhood of 150k, I don't think the economy of a bandage regulator should be a significant factor. The MC-614 with the entire harness costs around $350 and installing it is a plug and play process that requires little mechanical skill and no electrical knowledge. Particularly for a warp core equipped coach, since the shore side battery charger is so anemic, alternator charging is essential.

We've just got 800ah but we're still planning to carry a properly programmed MC-614 spare from Nations and we're even thinking about carrying a replacement inverter. None of this is inexpensive but considering the initial purchase cost of the RV, IMO it's an acceptable insurance premium.

I guess we have different definitions of "significant" cost. At $35 and the size of matchbox, while also being a plug in, I wouldn't see a reason to carry the expensive one which you can get in a couple of days if you need it after the emergency repair. There is, of course, the case where the regulator failure was caused by something else in the system. In this case a would rather fry a $35 regulator than one that cost 10X that.

The first generation of RT compressor fridges were set up to run on 12V or 120V but I believe the current generation is 12 volt only.

It's not easy to verify this empirically because the battery disconnect shuts off the voltmeter. If the meter was connected to the battery side of the disconnect switch, it would be easier to demonstrate.

There is something that; puzzles me about this arrangement. When unconnected to shore power, if the main battery switch is in disconnect, the inverter is inoperative. It needs a basttery output to function. I get that. Now, if you hook up shore power, even with the main battery switch off, you can still light off the inverter. What is the source?

Another question: you describe all the charging sources to be in parallel at the lithium charging port. If these charging sources are in a constant current (bulk) mode, with respect to the load, they apparently act in concert with one another. But if these sources are in a constant voltage mode, the load becomes selective with respect to which source is recognized and only recognizes the highest of competing voltages at the input. How is this phenomena dealt with in a condition where the alternator and solar panels are simultaneously attempting to charge the batteries?

That is correct. I have forgetten compressor fridge does not use ammonia.
Thank you.
