• Does Bargman Trailer Clearance Light 30-17-815 Include Foam Gasket?
• I would be happy to help! The Bargman Trailer Clearance or Side Marker Light w/ Reflector - Incandescent - White Base - Amber Lens # 30-17-815 you were looking at does not include the foam gasket to go between the light and the trailer, but you can add one by using the Replacement Foam Gasket for #178 Clearance Lights # 30-17-034. I included a video of the # 30-17-815 for you to take a look at.

• Recommended Suspension Enhancement for 2021 GMC Sierra 2500
• For your 2021 GMC Sierra 2500 4WD I recommend the SumoSprings Rebel Custom Helper Springs - 2 Piece - Rear Axle # SSR-203-40-2. These jounce-style springs have a 3,000 lb capacity and will keep your vehicle level while you're towing. They also help to absorb bumps and shocks while minimizing sway. Unlike airbags, they do not require any maintenance. These springs will also have a minimal impact when you aren't towing so you won't experience a stiff ride without your 5th wheel trailer. I...

• Tire Chain Fit for 35 x 11.5 x 20 Tires on 2016 GMC Sierra 2500
• I spoke with my contact at Titan Chain, who recommended the # TC3235CAM. He said that the width is correct, but the chain might be a couple of inches longer than what you actually need, but once you've fitted it to the tires you can always use bolt cutters to remove the excess for a perfect fit. The chain set includes cam tighteners for a good fit, but separately available tensioners like part # TCOA2 would be a good addition to ensure a tight fit. I've linked to a demonstration video...

• Recommended Above Bed Industry Standard Rails and Install Kit For 2016 GMC Sierra 2500 W/ 6-1/2' Bed
• The outboard 5th wheel mounting brackets are vehicle specific, so the brackets off of a Ford F-250 will not fit your 2016 GMC Sierra 2500 W/ 6-1/2' Bed, The outboard brackets are sold with the rails, so I recommend going with the Curt Custom Fifth Wheel Installation Kit for Chevy/GMC - Carbide Finish # C16411-204 which is confirmed to fit your Sierra, and will provide the correct brackets, rails, and mounting hardware to use your Reese R20 5th wheel hitch. I included a video of the #...

• 5th Wheel Hitch Installation Kit for 2018 GMC Sierra 2500HD Long Bed
• For your 2018 GMC Sierra 2500HD 8' bed without the OEM prep kit, I recommend using the Curt Custom Fifth Wheel Installation Kit # C16411-204. The custom fit under bed brackets use factory holes so that you aren't drilling into the frame and their finish closely resembles the undercoating on your truck. Don't forget the In Bed Wiring Harness # 41157 to move a 2nd 7-way receptacle into your truck bed so that you are not stretching your wiring over your tailgate and bedsides. If you still...

• Can Just 5th Wheel Hitch Be Replaced Or Do 5th Wheel Rails Need To Be Replaced As Well?
• The 5th wheel rails you had installed in your 2020 GMC Sierra 2500HD with 6-3/4' bed are industry standard rails so you will be able to just switch out the 5th wheel hitch. Since your truck has a short bed the sliding Curt A20 # C16541 would be the best option and honestly I am surprised they didn't set you up with a sliding hitch to begin with as a fixed hitch is really only recommend for 8' bed trucks. Another option is to replace the base of your current A20 with the slider base #...

• Recommended Trailer Hitch and/or Extension for 2017 GMC Sierra 2500 with Service Body
• For your 2017 GMC 2500, the service body issue isn't solved with just a hitch swap. Instead you will need a long ball mount like # BM20 or a hitch extender for the additional clearance needed. The addition of a hitch extender will reduce your hitch capacity by 50% unless you are using the Torklift Supertruss system. If you have a heavy trailer, I recommend using the TorkLift SuperHitch Original Trailer Hitch Receiver - Custom Fit - Class V - Dual 2" Receivers # TLC1211 which is compatible...

• Can Trailer Be Disconnected At Angle With Demco Autoslide 5th Wheel Hitch On 2015 GMC Sierra
• We do have an Autoslide fifth wheel hitch that may work for you. It is the Demco Hijacker, part # DM8550034. I called my contact at Demco and asked about disconnecting and the angle it can be detached. They told me that there is a 10 degree angle that the trailer can be disconnected to with the Autoslide. Since the opening that the king pin slides into has a limited amount of movement, trying to detach the trailer at a sharper angle would not work. With the Autoslide you have an additional...

• Best Fifth Wheel Hitch Recommendation for a 2015 GMC Sierra 2500 Short Bed
• Since you have a short bed truck you are going to need to get a slider fifth wheel hitch to allow you to make tight turns. Since getting out and operating the slider every time you get to a parking lot can be a bit of a hassle I would recommend the Demco Hijacker AutoSlide part # DM8550022. This hitch will automatically slide back when making tight turns. If you are looking for the best setup this would be it. The rail kit you would want would be the underbed kit part # DM8551010 that...

• There are a couple of options for snow tire chains that fit the 275/70-18 tires on your 2022 GMC Sierra 2500, and the best chain for your truck is going to depend on what type of weather you find yourself having to drive through most often, mostly snow, or if there is also a heavy dose of ice mixed in. - Mostly Snow: Titan Chain Alloy Snow Tire Chains Diamond Pattern - Square Link # TC2533 - Snow And Ice: Titan Chain Snow Tire Chains - Ladder Pattern - V-Bar Links # TC3829 The diamond...

• Highest Capacity Front Mount Trailer Hitch for 2021 GMC Sierra 2500
• The only front mount trailer hitch option we offer for a 2021 GMC Sierra 2500 is the Draw-Tite Front Mount Trailer Hitch Receiver part # DT57MR which has a 500 lb vertical load limit. There are no options from EcoHitch/Torklift at this time for Chevy models. If you need help moving a heavier trailer you'll have to look into a dolly like the Trailer Valet XL Trailer Dolly with Chain Drive part # TVXL25 which uses a drive system for easy maneuvering.

Like Firestone's Ride-Rite, the Air Lift helper air springs have the same weight capacity, but include internal jounce bumpers for added protection.
