• Will No-Drill Mounting Clips for EZ Connector Replace Dual Flap Receptacle on GMC Sierra
• The No-Drill Mounting Clips for EZ Connector # 319-S7-60B2 referenced in your question will replace both the 7- and 4-Way receptacle on your Sierra 3500. There is not a mounting clip available from EZ Connector that would replace just the 7-Way portion and leave the factory 4-Way portion intact. I have attached an image of the instructions just so you can see exactly how this installs on your truck.

• Why Does B&W Companion For 2021 GMC Sierra 3500 With Prep Package Need Padlocks Removed When Towing
• That's a good question, and it comes down to engineering and strength. The pins that hold the Companion in place to the puck system of your 2021 GMC Sierra 3500 were engineered to withstand what are significant forces on the hitch while towing with the Companion installed in the truck's puck system. The padlocks, however, were not designed with this type of constant force in mind, and using them while towing could lead to failure. So while I know it's not the most convenient thing in...

• Recommended Brake Controller & 7-Way Plug For 2017 GMC Savana 4500 Cutaway
• If your 2017 GMC Savana 4500 Cutaway came with the factory tow package then # HM40975 would plug into a factory harness already present under the van. It is usually tucked up above the spare tire or in that general area. For a brake controller I recommend the Prodigy P3, part # 90195. It's the easiest to use and most reliable controller we carry and one of the best on the market. The LCD takes the guess work out of using it and troubleshooting any errors that may come up along the way. If...

• Can Pace Edwards Beclocker Rails Be Cut Shorter to Fit 2021 GMC Sierra 3500 With Toolbox
• I reached out to Pace Edwards and found that it is possible to cut the rails shorter on the Pace Edwards Bedlocker Retractable Hard Tonneau Cover - Electric - Aluminum - Black # PE44CV. This would allow the cover to fit along with your toolbox on your 2021 GMC Sierra 3500. The one thing to keep in mind should you choose to do this is that the warranty will no longer be valid if you cut the rails.

• Will Air Bags for a 2018 GMC Sierra 3500 Fit on 2022 GMC Sierra 3500.
• Although I do not know all of the changes in the rear suspension between the 2018 and 2022 GMC Sierra 3500, I can tell you that the fit will depend on the air bag. Some of the air bags that fit the 2018 are also confirmed to fit the 2022, some are not. For example, the Firestone Ride-Rite Air Helper Springs # F2613 are confirmed to fit the 2018 and 2022 Sierra 3500.

• How To Determine What A Good Ignition Source To Install A Firestone Extreme Duty System Is?
• In order to determine the correct 12v, 30 amp, ignition activated power source for your Command I Xtreme Duty Compressor with Analog Gauge, Air Tank, and 25' Hose # F2543, you will need to physically test with a multimeter # PT29ZR, or refer to your owner's manual for which circuits come on with the ignition, and which ones are at 30 amps. Unfortunately, we cannot tell you which circuits those might be, as these will vary from vehicle to vehicle. I have attached a piece of the wiring...

• How Does Roadmaster Even Brake System Connect to Vehicle That Has Battery Disconnected
• Great question. So since the Roadmaster Even Brake part # RM-9400 does require a power source from the towed vehicle to operate and since the 2020 GMC 2500 Sierra does require having the battery disconnected when it's being flat towed what you need is a Roadmaster Outlet kit part # RM-9332. Basically this wires directly to the battery and provides an outlet for the braking system to draw power from while the rest of the vehicle is disconnected.

• Are SumoSprings Recommended for 2020 GMC Sierra 3500 That Squats With 5th Wheel Hooked Up
• I highly recommend using the SumoSprings suspension enhancement on your 2020 GMC Sierra 3500 Denali if your truck is squatting that much. The correct kit for your truck is: - SumoSprings Rebel Custom Helper Springs # SSR-203-40-2 The reason you want to use these springs is because when you have additional capacity in the bed of your truck and you start to sag, the front of the truck will also rise. When that happens, your Sierra won't handle as well as it should because the front tires...

• What is a Safe Minimum Height for a Cargo Carrier?
• A hitch mounted cargo carrier doesn't have a specified height requirement. You are correct that the longer the carrier extends the less ground clearance it will have on an inclined angle like a driveway. Some carriers have a rise integrated into the shank for that very reason like # E98874. This carrier has a 2 inch rise to change the angle. If you will be towing on level ground, a minimum height of 8 inches is enough for the suspension travel, but I personally would shoot for 12 inches...

• I would be happy to help you answer those questions but I want to start out by saying that you will need the Firestone Ride-Rite Red Label Extreme Duty Air Helper Springs item # F2709 for your 2020 GMC Sierra 3500.

• I do have options for you but I called my contact at Camco and they told me that the top part on the Cyclone RV Plumbing Vent part # CAM40597 that rotates is not designed to be removed. I went out to our warehouse and tested this myself to confirm that the rotating head cannot be removed and put back on. If you are looking for a lower profile vent I recommend the Camco RV Replacement Plumbing Vent part # CAM40033 which comes with both the putty and screws needed for installation. We also...

• Bypassing Factory Brake Controller and Installing Aftermarket Model on 2018 GMC Sierra 3500
• There isn't anything like an autonomous controller that would step up if the factory controller fails. I'd simply bypass the existing factory brake controller. The GM ITBC, although it works better now than the earlier models has been problematic enough that Tekonsha who provides many of our aftermarket brake controllers has a technical bulletin that specifically addresses how to bypass the factory controller. Let's just say you aren't the only one that's had problems with the factory...
