Does anyone, with MultiPro tailgate, have an Undercover Swingcase (or similar) toolbox installed. Apparently, Undercover states it doesn’t work with MP tailgate. But, however, GMC offers one as an accessory. The only thing they say it doesn’t work with is CarbonPro bed. It is marketed as an Undercover product. Just wondering if anyone has gotten one and made it work?
 

I have one on my passenger side.

Won't fit with the stick on the driver side.
 

I was JUST out there looking and I figured that was the case, with stick!

Just to verify, you have a new body style with MP tailgate and a passenger side swing box worked?

Undercover finally responded and confirmed what Y’all had already told me.

“Hi Ryan the SC104P will fit your truck but the SC104D will not due to the assist handle hope this helps thanks”
 

Has anyone figured out how to install the undercover passenger side toolbox with a carbon pro bed?

So, it looks like my 2024 AT4 should be fine....I see yours is a 2022, but it looks the same. I had a swingcase in my 2015 Silverado and loved it, but it was driver side, so I knew it wouldn't work. All the sites say even passenger side is not compatible.

I finally bought and installed a swingcase in my 2024 AT4 2500.

Are you still able to access the 110 outlet in the bed? I don't see the outlet in your 2nd pic.
