30A to 40A trailer fuse
Our TV is 2012 2500HD D/A. We at times lose our refrigerator while driving. It runs off an invertor instead or propane. I have found that the 30A 12v fuse under the hood is blown. Online shows that it...

Ours came with a 40a fuse in Stud 1, but IMO that is not the problem. Never saw more than about 20a using the 7-pin, but had problems at times back at the 7-pin bumper end with corrosion shorts etc. A short back there or with the trailer's end of it is more likely to blow that fuse IMO.
The inverter should be on the house batteries with good fat wiring and get its amps for the fridge from that. The 7-pin just helps a bit.
