Dragging the 7-way connector

I thought of that scenario as well. For the last leg of our trip, I laid down on the ground and pushed real hard (with a wiggle) to ensure the plug was seated properly. It staid until I got home. It was possible that I was in a hurry and set up properly.

Really?? I think that everyone here is bright enough to figure out that the cover of the truck's plug latches the 7-way plug in place and that if the plug is not seated properly the cover doesn't latch.

If you have to jimmy with the plug to get it to work, then there is clearly an incompatibility between the two plugs and one needs to be changed. Obviously, that would be the one on the trailer cord since you can but them for around $7. Most of the trailer manufacturers use Bargman plugs/cables and they have known compatibility issues with anything but another Bargman plug, which the truck manufacturers are not using.
Just go buy a Pollak plug, put it on and go camping.

The OP implies that he was not aware that the door was a latch. Go back and read for yourself.

If the spring on the door is good and it's latched, it's IMPOSSIBLE for the plug to come unplugged without breaking something.

Even if the plug was yanked because the cord was too short... It would break the door or yank the wires out of the plug. Surely the OP would have noticed either of those things.

I only mentioned it because I have made that mistake myself when I was in a hurry. Luckily the plug did not come unplugged on the road, and everything worked fine, but I noticed it wasn't latched when I got to my destination.

I had to replace my truck plug as the spring the closes the door / holds the plug in had gone bad (The plug door just flopped closed no spring).... So the plug would not stay in long.....Luckily I have two plugs I can use the other, having a fifth wheel until I could change the bad plug.

I have worked on many trailer connectors and there are as many slight variations to 7 way plugs and cord ends as there are trailers, the biggest issue I have seen is the one piece molded cord ends have deviated from the original Pollak design. I agree with Bob Landry, cut off the molded end and put on a Pollak end. Make sure the latch works when done.

I went to the dealership last week to get a replacement 7-way connector/harness to replace the damaged one. It has a Pollak connector on it. Thanks for all your input. I guess it was an accident waiting to happen, had my Palomino for a couple of years and this issue just came up on my last trip.
