There must be a way to do this with a.....2017 Silverado

If it were mine, I would change the boat plug to a 7way plug and just hook up the 4 wires and be done with it...

That won't solve the problem either, because then all he can do is plug in the boat trailer

he needs lights / power in his camper while also towing a boat trailer.

why would you plug both in at once:h

I couldn't find an adapter that worked for me so I wired the 4-pin through the 7-pin connector.

You only need to remove the 4-pin door to be able to use both sockets at the same time.

Just remove the spring door

The door provides a retention stop on the seven pin side that would be defeated if removed.

Just had to chime in. When I bought my 05 Chev I had them hook up the 7 pin in the box, as said by many here. I pull a boat, cargo trailer, and utility trailer. The utility trailer is a 4 pin, so I bought an adapter that the 4 pin hooks into, which fits the 7 pin on the bumper.

Had the same problem on my 2013 Sierra

Walmart sells a replacement receptacle. It has both types of connectors in one housing. It was about $20.

Remove the existing receptacle from the bumper and unplug the assembly from the wiring harness. The new unit plugs into the harness and then screw the receptacle into the bumper.

Took all of 10 minutes to install.

Hope this helps

Can't remember the last time I used the truck/camper and didn't have a trailer hooked to it............

Mkirsch, that may be the numbers of truck campers with trailers In your neck of the woods, but there are thousands up here in western Canada.
I was in a small town ( pop 3000) near where we camp as we went in to buy some grub and " refreshments " for the weekend.
Because of the new truck and camper we bought we have been looking at truck/ camper / hitch combinations over the last few months to see what will best suit our needs.
Yesterday we were looking and talking with 4 different people in town that have trailers of some kind behind there truck camper combanations.
Up here there are lots of people with more than one RV parked in the back yard. Lots of guys have a camper for hunting and they pull a utility trailer of all sizes and shapes behind them for the equmpment .
The combination of truck / camper and trailer are a common sight up here. Also when I had my 5Th Wheel I installed my second 7 post plug up near the front of the box in my truck which made it easy to plug in.
The second 7 post plug in the bed of trucks is a very common sight.

Poor design, because one person in a million has a weird corner case where they need both connections at once?

So only 1 in a million pull a boat with a truck camper?? Seriously?

Yes, and I think that estimate is on the high side.

There are hundreds of millions of trucks on the road. Only a few thousand of those carry truck campers. Only some of those carrying truck campers also tow a trailer of any sort. Only some that tow a trailer tow a boat. Only some that tow a boat do not have a dedicated plug in the bed of their truck for the camper. By the time it filters down there are not many, maybe couple dozen, with this problem.
