Wow! Great information here. Glad people are working this out, and the information is being spread. I checked my 2021 Reflection travel trailer, and my 110AC wiring is completely different from what is shown in your 5th wheel pictures. So at least on my trailer, this does not appear to be an issue.

I didn't think there was enough slack to get at the burn. I think I'll pull that receptacle and tape up my wire.The insulation is burned, but the wires are likely fine.
@S&M_G Residential receptacles will likely not work well in most cases in an RV. Residential receptacles need to be installed in an 1104 steel box. That box is deeper than most RV walls are thick.

Perhaps a heat shield is better than tape, as that boiler flue (chimney) gets very hot & could burn through the tape over time. Just a thought.
Good luck & thanks for the tip on the outlets!!Sadie & Matt

Well, when you see the rv rec's in no box at all, I thought they had special provisions.
Being in Canada I'm not overly familiar with your code but I believe you can only use that box with a receptacle and only one cable entering. Not an in and an out like most receptacles.2018 Dodge 3500 6.7 Cummins w Aisin and 9 cup holders

I've mirrored, cell phone pictured and tried everything I can come up with and cannot see the power wire anywhere next to the refrigerator. I guess it's whomever was doing the wiring that day.Joseph

On the box I linked to, there are two slots for wires so an electrician can run an "in and out" if needed. One on the bottom, and one on the top. Or it's permissible to run two wires into one slot. These shallow boxes are difficult to work with because there's not a lot of room for wires, but they will work if needed in thin RV walls where a standard box won't work. It's also difficult to install a GFI outlet into one because of the depth.

If I read 314 correctly, the box allows three conductors. The outlet counts for two.
But as I previously said, I'm a Canadian electrician and may not be reading the USA code table correctly.

I saw this box mentioned. Carlon B117RSWR

It looks to have enough box fill room for 2 NM 14 cables and a duplex receptacle.

I zip-tied the mess away from the burner flows and installed a heat shield in one place, so I should be fine now. But boy am I PO'ed that the RV industry is allowed to get away with selling a product so sloppily built that it results in safety hazards.So hard to believe and understand

If you try to dig into what these RVIA requirements actually are, you quickly come up against a "members only" firewall. Those "members" of course, being the RV manufacturers.
Motorhome RVs are different. They must meet requirements set by MVMA (Motor Vehicle Manufacturer's Association) and NHTSA (National Highway Traffic Safety Administration). An entirely different world where requirements are not set or inspected by the manufacturers themselves. There is likely a reason that motorhomes are so much more expensive than towable RVs.

Hi. Glad I found this forum. First post. Complete newbie and have owned a TT just over a month. My question is if somebody can confirm that this particular safety issue only applies *IF* you have a dual power fridge i.e. one that runs on both 12v and propane? And it's the propane part (exhaust pipe) that's causing the issue? If that's the case, that might be good to add to the original post for newbies.2021 Grand Design Transcend xplor 261BH TT
