4-Way Wiring Harness Compatibility For a 2012 Mercedes-Benz GLK 350
Yes, the Curt Powered Tail Light Converter # C59236 is confirmed to fit your 2012 Mercedes-Benz GLK 350. This 4-way harness will require you to splice into your tail light wiring for the signal wires of the powered converter. If you would prefer not to splice into your wiring we do have the Tekonsha ZCI Circuit Protected Vehicle Wiring Harness # 119250KIT that uses sensors that detect when power is traveling through the wiring to trigger the signal wires for the 4-way harness.

Adjustable Ball Mount For A 2014 Mercedes Benz GLK
To get your ball to the height you are wanting on your 2014 Mercedes Benz GLK I recommend using an adjustable mount. I recommend the B&W Tow & Stow 2-Ball Mount - 2" Hitch - 5" Drop, 5-1/2" Rise - 7.5K - Black Item # BWTS10038B. It provides a 1-7/8" ball and a 2" ball for different trailer couplers and fits 2" receivers. It is going to provide a 5-1/2" rise so it is going to provide the adjustability you are looking for. I recommend making sure the trailer doesn't exceed the weight capacity...

Recommended Wiring Harness For 2015 GLK-350 Base
The Curt Powered Tail Light Converter with 4-Pole Flat Trailer Connector # C59236 is not confirmed to fit your 2015 Mercedes-Benz GLK-350. It is a confirmed fit for the 250. The only wiring harness we have to fit your GLK-350 is the ZCI Circuit Protected Vehicle Wiring Harness w/ 4-Pole Flat Trailer Connector and Installation Kit # 119250KIT. This wiring harness uses zero-contact-interface sensors, so there is no wire splicing, but it will require a power lead from the battery.

Solution to Keep Hopkins Collapsible Vehicle Trunk Cargo Organizer from Sliding on Rubber Mat
The Hopkins Collapsible Vehicle Trunk Cargo Organizer # HM74113 does come with hook and loop fasteners (like Velcro) that you can add to the bottom of the legs which would help to grip a carpet floor. If you have a rubber mat then it's possible that the organizer could move around depending on how smooth it is and if there are any grooves or anything in it. I spoke with my contact at Hopkins who said that if you have a smoother rubber matt then a possible solution is to use two sides of...

How Much Weight Can the Kuat Transfer 2 Bike Rack Hold
The Kuat Transfer 2 Bike Platform Rack # KU74FR referenced in your question can indeed hold 2 bikes of up to 40 pounds each. This limit refers to the carrier's weight capacity, so I do not recommend sitting on the rack or applying any weight on the rack that exceeds this 80 pound total capacity. This carrier does feature a unique design though that will allow you to walk between the u-shaped platform so that you can easily use the rear bumper on your vehicle for a more stable seating surface....

Will Kuat Sherpa 2-Bike Platform Rack Fit 2014 Mercedes-Benz GLK
There is an easy way to determine if a bike carrier will work for your GLK. You will need a tape measure and a straight edge like a yardstick or a dowel. Place the straight edge vertically against the back of the rear bumper, letting it extend below the trailer hitch receiver opening. Then measure from the center of the hitch pin to the straight edge. This will give you the distance you need to clear the bumper. The Kuat Sherpa 2-Bike Rack, part # SH12B is a really nice bike carrier...

Hitch and Bike Rack Recommendation for 2013 Mercedes GLK350
For your 2013 Mercedes GLK350 the best hitch option is the Draw Tite part # 75774 as it will give you the most concealed look. For a bike rack I really like the Hollywood Racks Destination Bike Rack # HLY94FR. This is a platform bike rack that only weighs 20 lbs. The biggest drawback to platform bike racks has always been the weight of them, but with this rack you get the best of both worlds. The preferred attachment style with the lighter weight.

Does Plastic Trunk Shield Get Permanently Removed to Install Trailer Hitch on 2014 Mercedes GLK250
The plastic trunk shield should not have to be permanently removed to install Curt hitch # C13155 on a 2014 Mercedes GLK250. I believe that it was in reference to step 4 in the instructions I have linked for you. But as you can see it does not have to be removed. If you are going to be doing some towing I recommend etrailer ball mount kit # 989900. It comes with 2 ball mounts, 2 balls, a hitch pin with clip, and a storage bag. Trailer wiring will need to be obtained from a Mercedes dealer.

Recommended Towing Mirrors for 2012 Mercedes-Benz GLK 350
For your 2012 Mercedes GLK 350, I recommend looking at the K-Source Universal Towing MIrror # KS3891. These mirrors will fit most vehicle mirrors that are 4-1/2 inch to 11-1/2 inches tall and have a nice black plastic housing to provide a clean look that won't rust or corrode. They require a lip or gap between the factory mirror and the glass, so as long as the mirrors on your Mercedes have this design, these will work great. Another universal option if the K-Source design does not work...

Trailer Hitch Recommendation for a Bike Carrier on a 2011 Mercedes GLK350
For your 2011 Mercedes GLK350 the Draw-Tite hitch # 75774 and discontinued Hidden Hitch model 87636 are going to be identical (except for the name). The installation of these 2 hitches takes less time and thus installation is easier than the Curt hitch # C13142 which uses different attachment points on the vehicle. Based on the options I recommend trailer hitch #75774 which also happens to be the most popular option for GLK350 owners. I have linked the installation instructions for you. This...

Recommended Weight Distribution Hitch For Trailer W/ 440lbs TW, and Trailer W/550lbs TW
I would be happy to help! First the Curt MV Weight Distribution Hitch # C17050 you were looking at would be a bit stiff with the 440lb tongue weight you mentioned for your 16' Airstream, but is that figure what Airstream lists as the tongue weight, or what you measured? I would use a tongue weight scale to measure the tongue weight of both of your trailers when they are fully loaded if you have not already, as the tongue weight figures manufacturers provide are typically the unloaded...
