    337RLS with 2021 GMC 3500 SB - Auto-Slider Hitch

    I have recently ordered a new 2021 GMC 3500HD standard box (OEM puck system) and am considering getting an auto slider hitch. My current truck is a 2017 F250 SB with a manual Reese slider and we have a 2018 Reflection 337RLS that requires air bags to level the truck/trailer combination. I am considering the Pullrite Superglide and the Demco Hijacker. My concern is the 3500HD (12,100 lbs. GVWR) will sit up higher and potentially have a nose high trailer and/or low rail/trailer clearance. Both hitch types will require an adapter to connect to the OEM puck system, which raises the hitch that much higher. This concerns me since the Pullrite has no hitch height adjustment, but the Demco has a 2.75" adjustment range.

    Is there anyone out there pulling a 337RLS with either of these hitches with a 2020 or 2021 GMC 3500HD? If so, do you have any unlevel/clearance issues?

    Thanks very much for your input.

    337RLS with 2021 GMC 3500 SB - Auto-Slider Hitch

    I have a 2020 GMC 2500 AT4HD SB that I tow our Reflection 311BHS with, I have the B&W companion slider and have had no issues with bed clearance or nose high issues. Also have never once had to use the slider function, itís nice to have but I donít see myself ever needing it and i have definitely had it at 90 degrees. The camper runs pretty level actually before and after switching tires to 35ís with a leveling kit. I do have the air lift 5000 bags that definitely help keep the truck level when towing. Itís been a great setup, love my GMC, but youíll find they love the DEF! Click image for larger version.

    I have a Ram 3500, 337rls, and an Andersen hitch. I can do a full 90į turn and I still clear the bed rails by a reasonable amount. I have a Truxedo Pro X-15 tonneau cover on order. In a couple of weeks we'll see how it all works with the tonneau cover.
