  • Recommended Thule AirScreen Fairing For Thule AeroBlade Edge Roof Rack Bars
  • The Thule AeroBlade Edge Roof Rack for Raised, Factory Side Rails part # TH7503 measure 39" long so I recommend the Thule AirScreen XT Fairing for Roof Racks 38" long part # TH72WV for the Aeroblade bars to cut down on wind noise.

  • Correct Size Thule Motion XT Rooftop Cargo Box for a 2007 Mercedes-Benz GL450
  • I spoke with Thule for you and confirmed that the Thule Motion XT Rooftop Cargo Box part # TH629906 is a fit for a 2007 Mercedes-Benz GL450 with factory roof rack. However, in order to be sure that you can open the hatch fully with the cargo box in place you'll need to measure the distance from the center of the front crossbar to the point where the roof and hatch meet on your roof. If it's more than 55" you'll be good to go but if not you might want to step down to the Thule Motion XT...

  • How to Carry Bikes on a 2015 Mercedes Benz GL 500
  • I do have an option for you but nfortunately, no trunk mount racks that we carry are confirmed to fit your 2015 Mercedes-Benz GL 500. You can add a roof rack like the Thule AeroBlade Edge # TH7503B-TH7503B (black) or # TH7503-TH7503 (silver). This is an aerodynamic roof rack that has a great look. It installs onto the rails of your Mercedes and can be locked using Thule's One-Key System Lock Cylinders # TH450400. Then add a bike carrier like the Thule UpRide, part # TH599000. The UpRide...

  • Recommended Bike Carrier For 2012 Mercedes-Benz GLK350
  • I called my contact at Hollywood Racks and asked about the # HRF2 and how it fits with your 2012 GLK350. They told me that the spoiler on the back of a GLK350 are not structurally sound enough for the hooks to attach to. In order for the # HRF2 to be able to fit your vehicle you would need raised side rails on the roof of the vehicle. They also told me that if you have crossbars on a roof rack they may be strong enough for the bike carrier but they have not tested this and cannot say...

  • Trailer Hitch and Wiring for 2015 Mercedes-Benz GL550
  • Curt 2-inch hitch # C13190 is a confirmed fit on your 2015 Mercedes-Benz GL550 so long as it does not have the Active Curve System. This hitch is rated for tongue weight (TW) of up to 900-lbs and for trailer weights up to 7500-lbs. According to my research the vehicle itself shares this 7500-lb towing capacity. Install instructions are linked for you. This hitch will not offer the exact same appearance as a factory hitch; the cross tube will be visible as you can see in the photo from...

  • 7-Way Trailer Adapter for Voltage Issues Between Trailer Mounted Brake Controller and Vehicle
  • Absolutely. You will want the Trailer Connector Adapter w/ Lamp-Out Sensor Bypass - 7-Way RV to 7-Way RV - Vehicle End # 20142 which has the load resistors inside to help with exactly what you stated. The 12v power supply will run through without issue to allow your Prodigy RF to function.

  • As long as your 2007 Mercedes GL450 has raised side rails that run front to back this Surco Safari Rack 5.0 Rooftop Cargo Basket # SPS4550-1101 should work for your vehicle. This cargo basket is designed to work on virtually every factory roof rack and should work very well for you.

  • Where To Mount the Malone AirFlow2 Roof Rack on a 2010 Mercedes-Benz GL450
  • The instructions for the Malone AirFlow2 Roof Rack part # MPG215 state to position the crossbars 700mm or 27" apart on center to start with. However, this is more of a minimum measurement and you can absolutely space them out further if you need to more evenly distribute the weight over your roof. There are similar systems for your 2010 Mercedes-Benz GL450 which have a crossbar spread of up to 60". The B and C pillars will offer the most strength on your vehicle's roof but Malone does...

  • Does Kenda 205/65-10 Bias Trailer Tire with 10 White Wheel Have an Offset
  • The Kenda 205/65-10 Bias Trailer Tire with 10" White Wheel part # AM3H480 is a 10" diameter x 6" wide wheel with zero offset. We do carry some wheels with an offset but we currently do not carry a 205/65-10 wheel and tire combo with an offset or a 10" diameter wheel with an offset.

  • Confirming Trailer Hitch Receiver Fit for 2013 Mercedes Benz GL 550
  • I reached out to the manufacturer and the Curt Trailer Hitch Receiver # C13102 rated for 3500 lbs is the confirmed fit for your 2013 GL 550. This is the correct fit from 2008 through 2013 models. The # C13190 is rated for 7500 lbs but is only a fit for 2014-2016 GL 550 models. Unfortunately with the # C13102 being the only fit for your vehicle, you will be limited to the 3500 lb max towing capacity. For your wiring harness, the only confirmed fit we have is the # 119250KIT which...

  • Trailer Lights Won't Work on 2011 Mercedes-Benz GL on Trailer With 4-Way
  • I'm not sure why U-haul would say it's fine when it clearly isn't, but the problem with the Mercedes is that there isn't enough power draw, so you'd need to use a lamp-out adapter: - 7-Way to 4-Way/5-Way Trailer Adapter for Vehicles with Lamp-Out Sensors # C35FR This will allow the trailer's brake and turn signals to recognize the signals coming from your Mercedes. If you were already using one of these adapters (I wasn't sure if you were talking about one of those or a 4-way to 7-way...

  • Swinging Hitch Mount Bike Rack Fit On 2011 Mercedes GL450
  • I would not recommend using a hitch extender with your FullSwing bike rack either. Normally an inch of clearance between the rearmost point of the rack and your vehicle is still a safe amount of space. We test fit the Yakima FullSwing # Y02465 on a 2013 Ford Escape that has 1-1/2 inches of clearance at the back. I have attached the review video on the Escape for you. There are a couple of reasons why I would not recommend using a hitch extender for your bike rack. A hitch extender won't...

  • Thule AeroBlade Edge Roof Rack for a 2010 Mercedes GL350
  • The original fit list from Thule for the AeroBlade Edge roof racks was not 100 percent accurate and we are finding things out like this from time to time. I did confirm with Thule that for your 2010 Mercedes GL350 it should be # TH7502-TH7503. Our fit guide will be updated accordingly. With the rack installed you can mount the Motion XT cargo box # TH629706. To determine if there will be any interference with the rear hatch when opened you would have to measure from the center of the...

  • Will Whispbar Rail Bar Roof Rack and Skybox Cargo Box Fit on My 2013 Mercedes-Benz GL350
  • I spoke with my contact at Yakima and he recommends going with the FlushBar system, parts # Y00442-0443 and Y00158, for your 2013 Mercedes Benz GL350. This roof rack sits higher which gives you added room to avoid the factory satellite radio antenna. As for a cargo box, you will want to take a measurement of your vehicle's roof to ensure that you have sufficient room so there is no interference with the liftgate. I am including a photo that illustrates where to take the measurements and...

  • Recommended Battery for a 12,000 Lb. Electric Car Trailer Winch
  • For a 12,000 lb. electric car trailer winch like the Bulldog Winch Trailer Winch part # BDW10040, I recommend a standard 12 volt lead acid battery rated up to at least 650 cold cranking amps (CCA). As long as the battery is rated up to 650 CCA then you should have no problem powering the winch on your car trailer. A 650 CCA rating is more or less a standard for a 12,000 lb. electric car trailer winch. However, every electric winch should have a recommended battery rating. If you can tell...

  • Trailer Hitch Needed for a 2013/2014 Mercedes-Benz GL450
  • Although the VIN would help to determine the model year of your Mercedes-Benz GL450, in this case the Curt Trailer Hitch Receiver # C13190 fits both a 2013 and a 2014 model year so determining which model year you have doesn't matter for the trailer hitch. If you let me know what you will be using the trailer hitch for I can make additional recommendations if necessary.

  • Will Curt C51180 Echo Wireless Brake Controller Work With 7-way Connector on 2014 Mercedes GL450
  • It sure will! The Curt Echo Brake Controller, part # C51180 will indeed eliminate any wiring in the vehicle cab. The Echo works wirelessly, and would allow you to use your smart phone to control the braking action. All it needs from your 7-way trailer connector is a functional 12-volt circuit from the battery. It's a pretty slick setup. Not only does it eliminate the need for any wiring in the cab, but it also eliminates the need to drill holes in your dash and hang a box from it that...

  • Parts Needed To Add Roof Rack to 2016 Mercedes-Benz GL 450
  • Since your 2016 Mercedes GL450 has factory raised side rails, you are correct that you will only need crossbars to mount your Thule Atlantis 1800 cargo box to your vehicle's roof. Thule's AeroBlade Edge is a great roof rack. I have used these crossbars on my own vehicle and I highly recommend them. For your GL450, there is the option of using the Aluminum crossbars # TH7502-TH7503 or the Black crossbars # TH7502B-TH7503B. These bars have a very clean installation look since the crossbar...

  • What Is The Purpose Of The Rear Support Arm On The Curt Trailer Hitch C13190 For 2013 Mercedes GL450
  • The rear mounting arm of the Curt Trailer Hitch Receiver # C13190 you were looking at for your 2013 Mercedes-Benz GL450 is designed to add extra strength and stability to the trailer hitch receiver, which is shown in its much higher ratings of 900lbs tongue weight and 7500lb trailer weight rating. I guess it is possible if you were rear ended hard enough directly on the receiver it could cause frame damaged, but that is pretty unlikely as it would first need to bend frame where your bumper...
