Expert Answers about GMC Terrain


  • Does Fuse 16 of 2015 GMC Terrain Need to Be Pulled When Flat Towing
  • We have to recommend you stick with all of the recommendations that GM makes for flat towing your 2015 GMC Terrain. If they released an update that it's important to pull the 16 fuse it's for a good reason and you should do so. To make pulling the fuse a bit easier we have the Fuse bypass kit part # RM-76517 that basically allows you to just flip a switch to kill the circuit instead of pulling a fuse out.

  • Are Rola Aero Crossbar Dimensions Compatible with Kayak Carriers
  • The Rola roof rack 59786 that you referenced is perfectly compatible with kayak racks that are designed for aero shaped crossbars like the Thule Hullaport part # TH834. The bar dimensions are very standard for an aero shaped bar so these would fit and work well.

  • 2015 GMC Terrain Roof Rack Recommendation for Thule Hullavator
  • For your 2015 GMC Terrain the roof rack I'd recommend for use with the Thule Hullavator part # TH898 is the Thule WingBar part numbers # TH711220 and # TH710401. This is a confirmed fit for your Terrain and will work really great with the Hullavator since Thule makes this too. The WingBars are aerodynamically shaped too which helps prevent wind noise. This configuration has been tested to work on your vehicle and with the Terrain so it will work really well overall.

  • Recommended Tire Chains That Work For Both 225/60-18 And 235/60-18
  • There certainly is a set of tire chains that will work for your 225/60-18 and 235/60-18 tires. I recommend Titan Chain Diagonal Alloy Cable Snow Tire Chains - Light Truck - 1 Pair # TC729DC. This kit comes with the rubber adjusters to keep the chains tight. Also keep in mind that you should always consult your owner's manual to determine if tire chains are able to be used on your vehicle; some only allow chains on the front or rear. I have attached a video that shows how to use this product.

  • What is the Right Fairing for a Yakima Roof Rack on a 2012 GMC Terrain
  • If you have a Yakima roof rack on your 2012 GMC Terrain that attaches to a naked roof (no side rails) then the recommended fairing is the 40 inch, # INA261. If you have the roof rack that attaches to the factory side rails that run front to back then you would need the 31 inch fairing, # INA260.

  • Recommended Replacement Pin Box For 1998 Trailer With Fabex 520 Pin Box
  • The replacement pin box I recommend for your Excel trailer is the 5th Airborne Premium 5th Wheel Air Ride King Pin w/ Sidewinder and Turret, part # RP61412. This moves the pivot point back 22 inches for extra clearance when executing turns. With this system you also get the benefit of the extended pivot point and the cushioned ride with the air spring. . The cost for any of the products we offer is on the product page on our website. Before going to a long pin box on your trailer you...

  • Why Circuit Protected Trailer Wiring for 2016 GMC Terrain is Better
  • The Curt T-Connector Vehicle Wiring Harness with 4 Pole Trailer Connector, # 56094, will fit your 2016 GMC Terrain and will work to operate the trailer stop, turn, and tail lights. But, it does not have a circuit protected or powered converter to protect your vehicle wiring. If given the option, I will always recommend the circuit protected powered converter, # 118494, because it is designed to protect your vehicles sensitive wiring. What it does is virtually eliminate the extra power...

  • Brake Controller Recommendation and Parts Needed to Install Brake Controller On 2016 GMC Terrain
  • Since brake controllers are not vehicle specific, any of the brake controllers you found listed in the fitguide for your 2016 GMC Terrain will work for you. The note about "without factory wiring" references that GMC did not pre-wire the Terrain in the factory for a brake controller to be installed. For an electric brake controller, I recommend the Tekonsha Prodigy P3 Trailer Brake Controller # 90195. This is our most popular brake controller for your Terrain. The Prodigy P3 features...

I included a video of the # 118264 being installed for you to take a look at.

  • Recommended Trailer Hitch and Trailer Wiring for 2017 GMC Terrain
  • We have both Class III hitches with the 2 inch receiver tube or the Class II with the 1-1/4 inch receiver tube available for the 2017 Terrain. I'll typically recommend folks go with the 2 inch, as there are more hitch mounted accessories available and there isn't much of a price difference between the two. I'd recommend going with the etrailer brand # e98865 Class III hitch because it's very competitively priced and is just as high quality as the offerings from Curt and Draw-Tite. For the...

  • Hitch for my 2020 GMC Terrain with the Furthest Rear Pin Hole Location
  • Of the hitches available for the 2020 GMC Terrain the Curt Trailer Hitch Receiver part # C13307 has the furthest rearward pin hole location giving you the best chance for getting the tailgate open with your bike rack when you need to. The pin hole is 4" from the rear edge of the bumper Versus the DrawTite part # 76419 which is at 5". I have included a video for you of the installation process to check out. If you need wiring for towing a trailer the Curt T-Connector Vehicle Wiring Harness...

  • Steps to Take When Flat Towing a 2014 GMC Terrain Behind a Motor Home
  • You need to look at section 10-72 through 10-73 in the owners manual for your 2014 GMC Terrain. In addition to the 6 steps it lists to flat tow the vehicle there are also 5 steps to take after you are done towing for the day. It is very important to follow the instructions to the letter. Also, the manual only talks about front wheel drive and all wheel drive models. There is no mention of a 4x4. Quoting from the manual: To tow the vehicle from the front with all four wheels on the ground: 1....

  • Determining Which Reese Goose Box Fits 2021 Forest River Cardinal 5th Wheel Trailer
  • I would be happy to help you find the correct Reese Goose Box to fit your 2021 Forest River Cardinal 5th Wheel Trailer, but you will need to find the model of your pin box to determine the correct one. The 2020 bolt pattern you mentioned did not crossrefference to any pin boxes. To find the model of your pin box you will need to find the sticker on the pin box that has the model number, this is typically 4 digits. If you cannot locate the sticker just send me a picture of the sticker with...

  • Should I Use a Powered Converter 4-Way Flat Vehicle Harness On My 2010 GMC Terrain?
  • Your 2010 GMC Terrain does not require a converter for the 4-way trailer wiring. I do always recommend using a powered converter if one is available. Which for your Terrain the Tekonsha T-One Vehicle Wiring Harness # 118494 is available. For me the converter is protecting the factory wiring harness if there was ever a failure in the lighting system on the trailer. It also cuts down on the amount of power going through the tail light wiring on your Terrain. While it does require extra...

  • Recommended Bike Rack for etrailer brand e98865 Class III Hitch on 2015 GMC Terrain
  • For a swinging type bike rack that allows 100% access to the rear of the vehicle, I'd recommend the RockyMounts BackStage, part # RKY10002 which can handle 2 bikes weighing up to 60 lbs each with tires up to 5 inches wide, as long as the bikes DO NOT have fenders. For a hanging type bike rack with a 4 bike capacity for bikes weighing up to 35 lbs apiece that offers 100% access to the rear of the vehicle, the SportRack # SR2415 Ridge Swing would be a good option. We might have other options...

  • I recommend going with the etrailer trailer hitch # e98865 because it has the highest weight capacities of 350 lbs Tongue Weight (TW) and 3500 lbs Gross Trailer Weight (GTW). This hitch is confirmed to fit all models of the 2017 GMC Terrain so it will work well with your dual exhaust. I attached an install video for you to check out.

  • Roof Rack Recommendation for 2015 GMC Terrain with Naked Roof
  • For your 2015 GMC Terrain the best deal for a removable roof rack is the Rhino Rack Roof Rack part numbers # RRVA126B-2, # RRRLKVA and # DK225. Rhino Rack makes excellent roof racks that don't cost nearly as much as the higher end racks but they still function just as good.

  • Adding a 7-Way and Brake Controller to a 2012 GMC Terrain and Old Trailer
  • Trailers have combined turn signals and brake lights on the same circuit so you wouldn't tap into one of those otherwise the brakes would turn on with the blinker like you said. You are going to have to add a 7-Way connector to the 2012 GMC Terrain and to the trailer. And you will also need a brake controller. Since your Terrain already has a 4-Way you will just need # ETBC7 to add the 7-Way. I have included some links that show and explain the ETBC7 installation as well as the brake...

  • Best Brake Controller for a 2018 GMC Terrain
  • I do have a no wire brake controller option for you but your 2018 GMC Terrain does not have a plug in adapter port for a brake controller so most of the traditional brake controllers will require splicing. The best option we have for you that will not require any splicing is the Curt Echo Brake Controller # C51180. This controller installs on the trailer and uses your phone to set up so there will be no need to splice any wires on your new Terrain.
