Expert Answers about GMC Sierra New Body

• Recommended Cargo Carrier Step for Truck Bed Camper Access
• We do not have a cargo carrier that has a step, but we do have hitch extenders with a step integrated to allow you to have both. I recommend using the Buyers Products 12" Hitch Receiver Extension with Step # 3371804015. You will want to note that using an adapter like this will reduce the tongue weight of your trailer hitch receiver will be reduced by 50% which means your cargo carrier max will be reduced. This will work with any 2 inch receiver compatible cargo carrier. If you are...

• Ladder Rack and Tonneau Cover for 2007 GMC Sierra 1500 6-12 ft Bed
• Thule does have a ladder rack for your 2007 GMC Sierra 1500 6-1/2 foot bed that can be used with a tonneau cover. For that you would want the TracRac SR racks. You'd want the part # TH43002XT-501 or if you prefer the style that has an over the cab extension you would want the part # TH43002XT-501EX. This would allow you to use a roll up tonneau like the BAK Revolver X4S part # BAK62FR which is narrow enough to fit between the uprights of the TracRac. It also is considered a hard roll...

• Is a Sidewinder Required to Tow a 5th Wheel Trailer with a 2007 GMC Sierra with 5-1/2 Foot Bed
• You likely have an extended pin box on the trailer but it may not be enough to make 90 degree turns without hitting the trailer and the cab of your 2007 GMC Sierra together. But there is an easy way to figure it out. Step 1: Measure from the center of the trailer king pin back to the front of the trailer overhang. Write that down because it will be needed later. Step 2: Once a hitch is installed, the centerline of the hitch will be approximately 1-1/2 inches forward of the center of the...

• Demco Autoslide Fifth Wheel Hitch Recommendation for 2007 GMC Sierra that Can Also Tow Gooseneck
• We have just what you would need. To install a Demco Hijacker AutoSlide hitch you would instead need the hitch for industry standard rails part # DM8550035 and then for the rail kit to fit your 2007 GMC Sierra you would need the part # DM8552012-71. Once installed you would have the option to either use the fifth wheel hitch or the gooseneck adapter part # DM5996.

• Can You Add a Pintle Hook To the B&W Tow & Stow 3-Ball Mount for 2-1/2 Inch Hitches
• I do have options for you but there is not a pintle hook adapter for the B&W Tow & Stow 3-Ball Mount part # BWTS20048B so the only way to obtain a pintle hook with the Tow & Stow feature is to purchase the B&W Tow & Stow Pintle Hook with 2-5/16" Ball part # BWTS10056 separately and then use the B&W Hitch Receiver Reducer Sleeve part # BWRHXA2182 with this. That said, if you purchase the Curt Pintle Hook with 2-5/16" Ball part # C45908 and the Replacement 2" and 2-5/16" Dual-Sided Ball...

• How Does a Prodigy P2 Brake Controller Install in a 2007 GMC Sierra Truck
• On your 2007 GMC Sierra there isn't a plug for installing the part # 90885 as the vehicle doesn't have a port to accept it. To install a controller in your truck requires wiring it to the 4 wires under the dash of the truck that are present there. I attached a help article that covers this plus an install video that shows the controller being installed as well.

• Recommended Fifth Wheel Options For 2007 GMC Sierra Crew Cab With Short Bed
• With the length of the truck bed in your 2007 Sierra, a standard sliding fifth wheel hitch will not provide enough clearance for you to execute turns when towing. There are two ways you can go at this. I recommend going with the Demco Hijacker Autoslide, part # DM8550040. This hitch gives you 22-1/2 inches of additional clearance so you can make those tight turns. For above-bed rails you can use part # DM8552013-71. If you want full use of your truck bed when you are not towing I recommend...

• How to Tell the Difference Between 2007 Chevy or GMC Silverado or Sierra Old and New Body Styles
• To determine if your 2007 GMC Sierra is the old or the new body style all you have to do is look at the back of the truck. If it is the old body style (Classic) then it will have amber turn signal lenses at the rear tail lights. New body style models will not have amber lenses and will also have a large logo in the center of the tailgate. I have included a picture showing old and new body styles side by side. The trucks are Silverados but the same differences apply to the Sierras. If...

• Slider Hitch Recommendation for 2007 GMC Sierra 1500 New Body
• Since your truck bed is shorter than 6 feet long there's only one slider hitch that will have enough clearance to allow you to make tight turns and that's the Demco Hijacker Autoslide part # DM8550040 which slides back 22-1/2 inches which is about twice as much as other options. Also since this hitch slides back automatically you wouldn't have to worry about getting out and manually operating the slider either. Then to install it in the bed of your 2007 GMC Sierra 1500 you'd need the...

• Power Mirror Recommendation for a 2007 GMC Sierra with Turn Signals and Heat
• The K Source Custom Towing Mirrors # KS62093-94G that you referenced have all of the features you want, except for auto-dimming. None of the mirrors we offer have this feature though so this would be the best option I could recommend for you. I attached a review video for this product for you to check out as well.

• Why are Some Lights Listed as Over 80 Inches and Others Under 80 Inches
• The reason there are trailer light kits listed for under 80 inches and over 80 inches is that there are different lighting regulations for vehicles that have widths that are larger than 80 inches in width than ones that are less than 80 inches wide. You will need to check with your local laws and regulations on trailer lighting also. Check out the LED Submersible Right Hand Light # STL8RB and the LED Submersible Left Hand Light # STL9RB. These are stud mounted, submersible, rectangle lights...

• What is the Correct Diode Kit to Flat Tow a 2007 GMC Sierra 1500 New Body Style
• I show that for a 2007 GMC Sierra 1500 new body style, you will need to use the Roadmaster 4-diode kit, # RM-154. Your truck has a 2 wire system (combined brake and turn circuit) so additional diodes are not needed. There are diagrams on the product page, below the description, for wiring the diodes, and I have also included the pictures here. If the towing vehicle has a combined brake and turn circuit, you will use the first diagram. If the towing vehicle has separate brake and turn...

• Easy to Install Brake Controller for 2007 GMC Sierra 3500
• The easiest brake controller solution for your 2007 GMC Sierra 3500 is the Curt Echo # C51180 which plugs into an active 7-way and once synced to a smart phone is ready to tow with. Or you could use a standard controller like the Brake EVN # TK63VR which attaches to the brake controller wiring already present under dash.

• Brophy Truck Bed Camper Tie Downs for 2007 GMC Sierra 1500 New Body 8-Foot Bed
• If you prefer a stake-pocket-mounted tie down the Brophy kit # TDSF will fit most full-size, non-dually pickup trucks with straight fenders and single-wall construction. Drilling is required and this kit works with campers up to 8-feet in length. Other camper tie down fits on your truck depend on its exact configuration. The drop-down menu tool on the linked page will let you select your truck's configuration. As an example, for the 2007 Sierra 1500 long bed extended cab without step but...

• How to Charge Up a Trailer Mounted Battery While Driving
• The 12 volt circuit on a 7-Way trailer connector is not adequate for charging up a trailer mounted battery. At best it can maintain the current charge in the battery assuming nothing is drawing power from it. Solar power takes a very long time to charge up a typical 12 volt car-type battery so it will need a little help to charge up the battery. Take a look at the DC to DC charger # 331-BCDC1225D. With this unit you can actually charge up the trailer battery while you drive. It has inputs...

• Wiring Plug Recommendation for the 6-1/2 inch Oval Light part # BU70CB
• I checked with Optronics and they recommend the part # A45CB and part # A49PB for plugs to fit the 6-1/2 inch Oval Light part # BU70CB that you referenced. It could be that your # A45CB just isn't orientated correctly so that it installs correctly, or that you are trying to install the plug into the wrong pins.

• Replacing Rusted Out Gooseneck Hitch For Towing 5TH Wheel Camper With 2007 GMC Sierra 2500HD
• As the current gooseneck hitch on your 2007 GMC Sierra is rusted out I would not feel safe trying to use it for hauling a 5th wheel. I recommend replacing it with a B&W Turnoverball Underbed Gooseneck Trailer Hitch # BWGNRK1067. This hitch will fit your 2007 GMC Sierra 2500HD with either the short bed or a long bed. This will maintain your clean bed and not require you to install 5th wheel rails into your bed which can get in the way when hauling certain items. The gooseneck ball can...

• Recommended Transmission Cooler on 2007 GMC Sierra 2500HD for Towing Up Mountains
• For your 2007 GMC Sierra 2500HD with the 6.0L engine I highly recommend the Derale Dyno-Cool Remote Cooler with Fan # D12743. Since traditional aftermarket coolers still rely on airflow for optimal performance, a unit like this one that features an integrated fan is the best solution for applications like yours since you likely aren't driving too fast up and down those hills. This unit will do a great job of supplementing the factory cooler to keep temperatures down and since it has the...

• Reese Goosebox That Can Fit 2016 Rockwood Fifth Wheel with Reese Revolution Pin Box
• If the trailer has a Reese Revolution there's a very good chance the Revolution could be replaced with a Goose Box which is the best way to convert a fifth wheel trailer to a gooseneck. We've spoken with Lippert and Rockwood in the past and with similar Rockwoods they used the Lippert 1621 pin box which is what the # RP85FR was designed to replace. This would be the best solution based on what you are looking for.

• Should Second Weight Distribution System be Used with Second Trailer
• Your best option will be a second weight distribution system like the Reese Steadi-Flex part # RP66559 if you need a system that has a tongue weight range of 500-1,000 lbs. Reason being is that every trailer needs to have a very specific amount of spring bar tension from the WD system for it to work properly. Trying to use one system between two trailers will get frustrating as you will constantly have to be adjusting spring bar tension. Having two systems means you can set each system...
