'15/'16 side steps with gooseneck?

Adamrg · November 22, 2015

I am thinking about changing my trailer setup to a gooseneck, so I plan on adding a gooseneck hitch before taking delivery. I noticed the other day when I was building a Sierra on the website, when I select the gooseneck under bed hitch, it makes me remove the sidesteps. Is there something with the hitch that prohibits the mounting of the factory side steps?

Just a fluke, if you placed the order at the dealer it wouldn't kick the running boards out.

No info has been given regarding the "factory" installed gooseck.

I am guessing GM is just farming the job out and really you are just getting a aftermarket gooseneck hitch, the spray in bed liners are aftermarket and down down the street from the factory.

I guess what I am getting at is I would rather find a dealer to install a B+W hitch and spray in liner myself after taking delivery.

Steps and hitch are no problem, probably a fluke with the build and price like SMiller stated.

GM uses Curt Industries for their 5th wheel and gooseneck hitches.

On 2016 model year HD, there is a new RPO code as well:

It was in fact an error in build site, I was able to get both the side steps and the curt gooseneck and nothing interfered with each other.

I did not get the factory bed liner because line x is thicker and I wanted the extra cushion. My only mistake was a lazy line x dealer that sprayed over all 9 bed plugs. I had originally hoped to remove and reinstall the plugs as needed with the removable tie downs just as you would from factory, but they have made that an impossibility now. I cut them out, but even if I reinstalled them it would take a beefy screwdriver or pick to grab them to remove. So I just cut the 4 corners out and stuck my toe downs in and there they'll stay
