• Will the Thule Motion XT Rooftop Cargo Box Fit on a 2018 GMC Terrain
• In order to determine whether or not the Thule Motion XT Rooftop Cargo Box # TH629806 will fit on your 2018 GMC Terrain you will need to take 2 measurements; you'll first need to measure to make sure your crossbars aren't more than 3-1/2" wide and 1-11/16" tall.

• Is There a Draw-Tite Trailer Hitch for a 2022 GMC Terrain
• I do have an option for you but Draw-Tite does not list the Draw-Tite Max-Frame Trailer Hitch Receiver part # 76419 as a fit for a 2022 GMC Terrain yet therefore, I recommend using the Curt Trailer Hitch Receiver part # C77FR which is a confirmed fit. The Curt hitch has a class III rating, 2" opening, and 4,500 lb capacity.

• Installing Roadmaster Fuse Bypass Kit
• The black cable on the Roadmaster FuseMaster Fuse Bypass Kit # RM-76517 should be running to the negative side of the fuse terminal. If you're getting power on the black wire then you have it attached to the positive side of the fuse terminal which would be incorrect. Flip the black and red cables the on the fuse terminals and you should be good. I've attached an installation video to help with the installation process for the Roadmaster FuseMaster Fuse Bypass Switch for Towed Vehicles...

• 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 Flat towing Equipment For A 2013 GMC Terrain AWD
• Your 2013 GMC Terrain AWD is able to be flat towed (all four wheels on the ground) but there are some steps you need to follow to get your vehicle ready for flat towing, which can be found under 'Dinghy Towing' in your owner's manual. Note: AWD models of the 2013 GMC Terrain are not able to be dolly towed (two wheels on the ground) and should instead be towed on a flat bed.

• Where Do the Trailer Wiring Harness Relays Install on a 2018 GMC Terrain
• For wiring harness # C94FR you may not need the relays if they are already present on your 2018 GMC Terrain. If the wiring harness works, then you can just hold on to them as spares. If it is not working, then they will need to be installed. Locate the fuse panel at the back of your Terrain. It is behind a little access plate on the driver's side. There are 3 relays for tow package wiring in this box. K1, K2, and K3. The relays will need to go in the K1 and K3 locations. The K2 spot is...

• Troubleshooting Pulsing Brakes With The Demco Stay-In-Play Braking System While Turn Signal Is On
• Demco stated that the pulsing that you've been experiencing with the Demco Stay-IN-Play DUO Supplemental Braking System w/ Wireless Coachlink Monitor - Proportional # DM86VR when your turn signal is activated is normal and usually caused by the sensitivity being cranked up too high and near the max setting. You can adjust the sensitivity of the inertia-sensing mercury switch with a knob on the front of the G-Force controller. Adjusting the sensitivity lets you decide how intense the change...

• Weatherproof Roof Cargo Bag Recommendation for a 2015 GMC Terrain
• For a weather-proof cargo bag that can basically fit any roof style the Rightline Sport 2 # RL100S20 would be a great choice. This bag measures 44" long x 36" wide x 19" tall and was designed for the roof of an SUV like your 2015 GMC Terrain. In order for something to be considered waterproof it needs to be able be submerged underwater and not allow any water in.

• Does etrailer Hitch Lock e98882 Have Weight Capacity
• Hitch pins and hitch pin locks like the etrailer lock # e98882 do not typically have weight capacities as they do not normally bear the weight of the trailer since the tongue weight pins the mount into the hitch tube. This would work well in a flat towing setup too even though the tongue weight isn't quite there.

• What Do Thule Roof Cargo Boxes Attach to On the Roof of a 2012 GMC Terrain
• The Thule cargo boxes like the # TH6358B that use the quick grip mounting systems are designed to attach to crossbars on the vehicle that run from left to right. For your 2012 GMC Terrain you most likely have crossbars but in case you didn't you would want the Thule Roof Rack with Evo Raised Rail Feet # TH710401 and 53" WingBar Evo Crossbars # TH711420 if you have rails on your roof that run from front to back. Or if the roof is totally naked you would need to install the Rhino Rack roof...

• Sizing the Solera RV Slide-Out Awning
• The Solera RV Slide-Out Awning, # LCV000168110 has an actual fabric width of 163". If the slide on your RV measures 153" (12'-9") from outside edge to outside edge then this will provide 5" of overhang on each side which works just fine. The Solera RV Slide-Out Awning, # LCV000168109 is one size down and has an actual fabric width of 157" that would provide a 2" overhang right/left. Either would work well I suggest taking into consideration if anything on the side of the RV where this...

• Can a 2020 GMC Terrain SLT Be Flat Towed
• From what I was able to find in the owner's manual, it doesn't look like the 2020 GMC Terrain can be flat towed; I do recommend confirming this in your copy of the manual to make sure. It appears that the front wheel drive versions of this vehicle can be towed with 2 wheels off the ground using a tow dolly like the Demco Kar Kaddy SS Tow Dolly with Disc Brakes - Foldable - 4,800 lbs # DM9713045. If you've got an AWD/4wd GMC Terrain, it will need to be towed on a platform with all 4 wheels...

• Comparing Blue Ox Patriot and Demco Stay-IN-Play Braking Systems for a 2017 GMC Terrain
• In regards to braking systems, there are portable options which take a bit of time to setup but can easily be transfered for vehicle to vehicle and there are fixed options which don't really require any setup but are not easily transferred from one vehicle to another. The best two options in these categories are the Blue Ox Patriot Portable Braking System part # BLU37TR and the Demco SBS Stay-IN-Play DUO Supplemental Braking System part # SM99251. These will both work just fine on a 2017...
