I reviewed the science (absorption cooling units), and it's easy to see why replacing the hydrogen with helium makes the units safer. This helium unit is made by, https://jc-refrigeration.com/
*
It's clear to me, that if you have the helium cooling unit, THEN add the ARP Fridge Defend electronic safety unit to it, you'll have a very safe RV refrigerator.
As soon as I finish my roof and ceiling project, I plan to do the above modifications to my Norcold 1200 (in my Dutch Star).

We may assume you never run your LP furnace or water heater while driving either. You do know all LP appliances in RV's are RVIA industry approved for operation while moving.
Now you know a house battery bank can explode, in our land yachts as well as water yachts.

No disrespect meant toward your friends loss. I truly hope they come out of this OK. I just get tired of people jumping to conclusions.

Hug your friends and tell them many of us are sending our prayers and good wishes their way.
I have a tiny (by comparison) 22-foot long Winnebago Rialta equipt with a 3-way Norcold refrigerator. Recently, while looking for a part at the huge Copart, USA salvage yard in Lexington, KY, I learned that blown tires may be reason number 1 for the destroyed RVs in their yard. But refrigerator fires are reason number 2---especially if the owners were keeping their RV fridge cool with propane while driving.

You do more backing up with your foot on the brake pedal and this is how the auto adjusters work.

Air brakes are different, they do not auto-adjust that way.

This thread has wandered a bit. I hope that the OP can find out what actually happened, causing the fire, and can post that cause.

The OP posted in #19, 20 & 27 that the rear brakes were the cause.

Glad to hear you got out okay.

Propane is always turned off while traveling. Don't have a propane water heater or furnace and I will take my chances on my eight (8) house batteries exploding but I will never take a chance with propane.

On a gas chassis for example its considered in Severe Service having a motor home coach body built on it which means a 2 year schedule for flushing out the brake fluid along with lubricating the caliper pins, slides and guides with a good quality high temperature silicone brake grease. Dragging brakes can also be responsible for early tire failures/blowouts from the higher temps they will be running at along with reduced fuel economy.
I lost my Vectra with the gas chassis to a sticking brake caliper on the right front wheel and we barely got out in time. The rub was that I didn't have time to take care of them myself so I recently had a service center flush the brake fluid, lube the calipers and service the front wheel bearings. The coach was not new and valuable enough to take them to court over it since the forensics would have cost too much to make it worth while especially since nobody was injured or died.
Here is a hint that can help prevent a stuck caliper incident: Drive the vehicle forward and backwards a few times before driving off tapping the brakes sharply to shake the dust off the calipers and help free them up.
The tow truck driver that showed up for my fire told me brake and engine fires are most common and that 99% of the time the contents of the refrigerator and freezer will be untouched so get some coolers and come right to the salvage yard to get food for the next few days and to salvage the pots, pans, dishes and any other items not too badly damaged that can be cleaned up. We found that he was absolutely right and also that most items in the cabinets were just a little smokey even though the first third of the coach had the roof burned off.

The same thing happened to our Workhorse Bounder. I was the one who serviced the calipers and changed the fluid before the fateful trip. One would think 'a' driver would know a caliper was dragging.....I never felt a thing until the inside rear tire blew from the heat(and no I had not installed TPMS yet). It was a three fire extinguisher fire and we carry two....it is very hard to extinguish burning rubber tire. If a trucker had not stopped and handed me a 2' tall fire extinguisher it would have burned to the ground.
If anyone doubts that a dragging caliper can get that hot, the 1/4" steel backing plates on the disc brake pads were melted completely through.

Appreciate the information. Are there any restrictions for older MH?

Here are several YouTube videos showing just how hot things can get with a 'stuck' brake caliper.
and
Which does give a good recommendation that one have a TPMS with temp monitoring.

Didn't the Workhorse caliper recall have something to do with them sticking? I wonder if this was a Workhorse chassis and whether the recall had been done?
I was following a gasoline tanker(!) down the long I-17 grade just south of Camp Verde, AZ yesterday and his rear trailer brakes were smoking like crazy. I was expecting them to burst into flame at any moment but he made it down the grade without incident. Not the vehicle I would want to be in if my brakes caught fire.
