[tentcamper]

I have 2 frame grounds that I have seen.

1st - on the tongue, you follow the bare un-insulated wire from the battery negative terminal. There is a ground lug that is screwed to the frame.

2nd - under the camper on the inside of the frame rail, or maybe the cross frame rail. Between the rear bumper and gray water holding tank nearer to the street side. Again there is a ground lug that is screwed to the frame and an un-insulated wire copper wire is there. The wire looks like it come from somewhere around the converter.

I will need to check for the ground that scrubjaysnest mentioned, or maybe that the same one as my 2nd ground mentioned above and they changed it?
