For those towing with an Andersen Ultimate, where do you have your 7 way plug? I am getting my gooseneck ball installed tomorrow, and I want to make sure where they place my plug will not interfere with the Andersen hitch or with RV when it turns.

In the bed of truck. Driver side half way between the front and the wheel well.

As said above but up high and close to the tailgate so you can reach in to plug.

You are always going to run into those that want the plug between the wheel well and the tailgate or between the wheel well and the front of the truck bed...Either place is fine as long as you mount in the recessed area...You should have enough length on the fifth wheel cable to fit either place. My fifth wheel setup went to the standard 7-way connection near the truck rear trailer hitch hookup without any issues...Roy Ken

When I had my 2012 Ram I mounted the plug up front just slightly ahead of the wheel well, it was ok there but had to climb on tire to get it plugged in. On my 15 Ram I had the 5th wheel prep with it and the plug is mounted just ahead of rear post behind the wheel well as seen in Cummins12V98's post, much easier to get to and out of the way. When I bought my Reese hitch for my 2012 it came with an adapter harness that's plug and play from the rear wire harness ahead of the actual plug so you'd still have bumper plug to wherever you wish to mount the new plug.

If it was me, I'd mount just inside the tailgate, if there's room. Easier to get too. If you mount ahead of the rear wheel, your might need a ladder just to plug in the cord because there trucks are getting so tall. When I had a truck with 5th wheel, I had the plug ahead of the rear wheel well. I hated it. Every time it rained you had to reach over the bed rail to plug in the cord and you'd wet. Just something to think about.

That's where I have mine. I've been plugging it in there for about 6 years with no issues.

Mine is in the bumper too. I'm installing one in the bed because the cord will rub on the tailgate and rub the paint. Just had the truck re-painted this past fall due to storm damage and I don't want a repeat.
I have been hanging mine over the tail gate for 12years and it has not rubbed the paint or worn the cable in close to 50K miles.

I just bought a new 5th wheel trailer and also use the Anderson adapter. I mounted the plug just inside the bed wall near the tailgate. For me, it was the perfect set up.

Mine in the exact position as this one. Works very well, and no issues.
With that said, shouldn't be any different that a regular 5'r hitch.

Same here

Thanks for all of the help. I was under the impression that the 7 way plug went in the floor of the bed, so I wanted to make sure it didn't interfere with the Andersen. I will make sure it is located on the side of the bed behind the wheel.

I installed mine in the left rear corner also. I didn't have a hole saw big enough to drill the required hole so I just mounted a bracket like you would use on the bumper. Just mounted it to the side right by the tail gate. I then used a plug and play harness I got off of ebay and ran the wire up the inside of the bed and out an existing hole. Works great and I now have two seven pin plugs to access.

Nothing unique about the Andersen when it comes to where u mount your 7-way. Same as any other 5er hitch

I'm thinkin there may be a "Lightweight" version they use. :B

I installed a plug in the left rear corner of the bed in my prior truck. The replacement truck I bought a couple of years ago had the factory plug on the bumper and it's worked so well I've not been tempted to install a second plug in the bed.

I used a "Plug-in" harness made by Curt and along with the new plug, the original bumper plug still works so you've got 2 live locations. It was super easy to install.
