Good luck with CW!

My information comes from going to Norcold and Dometic factory schools. In the seventies, You would be correct. According to both schools, the refrigerators of today, are able to be off level for over three weeks without damage.

Horsepucky!

ARP temp monitoring device shows increase in temps within just 20 minutes of coolant flow disruption

Nothing has changed in design of absorption refrigeration since 1920s
Still same process....heat ammonia into vapor, cool the hot ammonia vapor into a cool ammonia liquid, flash the cool ammonia liquid into a COLD ammonia vapor....absorb heat via low temp and high temp evap coils then gravity flow hot ammonia solution back to absorber tank cooling as it flows downward to be reheated and start process over.

Disrupt that natural/gravity flow process either by being off level or via crystals plating out...more overheating

DEATH.......damage is accumlative and permanent

Latent Heat.....it is all about controlling the latent heat
Low/disrupted coolant flow results in damage due to the latent heat ...plain and simple

Our TT will run about four days before the phantom loads run the battery down. No battery will shut down the frig running on propane.

I always remove the food between trips.

Camping World requires all perishable foods be removed because they can’t guarantee how long they’ll have the TT or how long they’ll have it plugged in.

Hopefully I get my TT back by tomorrow.

Horsepucky isn't a scientific term either Old Biscuit even if you do throw in a couple of terms like latent heat

The published allowable limits for off-level operation of standard absorption fridges are 3 to 4 degrees side to side of the fridge and 4 to 6 degrees front to back.

If you parked that much off-level (that is about 2 feet front to back of the motorhome and about 8 inches side to side) you would fall out of bed and you would need a gimbaled marine stove to cook on.

Agree, the fridge uses very little propane and the controls use very little battery. But once out of your control the shop might turn the propane off or do something else nutty.

Best to empty and clean the fridge and turn things off yourself.

I know it will not be easy because you are staying in it. That is why I always try to fix everything myself.

NEVER leave a camper at a service center with anything in the fridge, ever. Make sure the doors are open per winterizing instructions.

I left a few items in the fridge (soda cans mainly) and emptied the freezer.

When I got my TT back the next afternoon, the freezer was colder than the hotel fridge I put my items in.

Anyway, shower/tub water leak fixed. Back to TT living...
