I agree but if the trailer is properly grounded there would be no stray voltage to be felt since the frame is part of the ground

I just did some work on a melted neutral bar in my trailer and discovered that there is no ground to frame on the 120 volt side, only on the 12 volt side. The ground from shore power goes to the grounding bar and all the outlets ground wires go to that bar. The bar is isolated and there is no ground wire to frame anywhere that I can find, is this unusual? I can clearly see where the 12 volt ground goes to frame.

There should not be a connection between the neutral & ground in your trailer. The neutral & ground should be connected at the campground power supply. The trailer is an accessory plugged into the campground power. Just as there is no connection between ground & neutral for any appliance you plug in at home, such as heater, etc...

I know that already, my question was about the ground wire from shore power, in my trailer that ground wire DOES NOT connect to the trailer frame at any spot. The shore ground wire (120 VAC on 30 amp connection) simply goes to a ground bar and that bar is isolated from the trailer frame. My concern is creating a ground through a person from the trailer to ground.

Check in your converter. If it is wired to code, there should be a #6 wire connecting the converter ground to the trailer frame.

You can use an ohm meter to check - it there really is no connection between the ground buss & the trailer frame, there should be. Without one, you have a shock hazard waiting to happen.

I know there isn't a connection, I just thought there should be one and wondered if I'm right or not. It is already strange to me that the neutral and the ground are not bonded together in a trailer, so therefore I thought perhaps there was some reason to avoid the 120 volt grounds from bonding to the trailer frame (since it is the 12 volt ground already)
