No power to most outlets

[Aussieguy]

I had adequate room to install shallow boxes.

totally agree
plus you can install NON flush outlets on the counter OR under the high kitchen cupboards if you have too
lots of options

Never had my 30yr old boat's 120v fail either
they would never allow those RV press on, stab, wire pinchers
they did use solid romex style wires... just properly supported and clamped

Chances are the demand of the space heater caused a connection failure at any one of the outlets. Even one where the heater or extension cord is not or was not plugged in. (You should never use an extension cord with a space heater.) Most outlets are wired from outlet to outlet to outlet. The type of connections used are known as an IDC or Insulation Displacement Connection. This merely penetrates the insulation on the wire allowing contact to the copper conductor. These are NOT GOOD for high current or high wattage items.

You will need to unplug from shore power. Then open or pull each outlet from the wall and carefully inspect the points where the wires are attached to the outlet. Look for loose and/or charred connections. It may require replacing the outlet if there is any evidence of heating.

Personally, I have replaced all of the outlets in our trailer with good quality residential outlets that use screw terminals to make connections. The IDC types and stab connection types are crap! (IMO)

Thanks for the info, I have the same problem. I have tried about everything, replaced the GFCI, breaker, and opened up 3 outlets, so far, and have not located the problem..I agree the IDC outlets are garbage. I am beginning to think my problem may be in the first connection out of the breaker box, as I have power out, but not into the first box with GFCI in it. The line out of the breaker box, seems to go into another line, which then feeds the first box, the line runs under the stove and sink, so hard to get at. I'll keep plugging away and figure it out. I might end up just rewiring the whole thing. I can't believe they put out such crap!
