• Can the Glow Step Stow and Go Mounting Bracket Be Mounted Horizontally Under the Camper?
• I have a solution for you but I was able to reach out to one of my contacts at TorkLift and the GlowStep Stow N' Go Mounting Bracket # TLA7810 needs to be mounted vertically, not horizontally, because of concerns with the leverage required to hold the steps on. TorkLift recommended having an iron/steel plate mounted under your door, that hangs down a bit past the bottom edge of the camper, in order to mount the steps. This shouldn't interfere with anything on the camper or truck and would...

• How to Determine Correct Height Setting on Demco Hijacker Autoslide
• Thank you for providing those measurements! Since your 5th wheel hitch height is 47 inches, subtracting the bed height of 39 inches gives us the 8 inches you mentioned which is technically the setting you would need to use on your Demco Hijacker Autoslide # DM8550034. This poses a problem since the HIjacker is limited to a height adjustable from 15-1/4 to 18 inches tall. If your measurements are correct, this means that in order to tow your 5th wheel trailer with your 2019 GMC Sierra 2500...

• Can Curt Friction Sway Control Bar Be Installed on Driver/Left Side of Trailer
• The Curt Friction Sway Control Bar # 17200 is designed out of the box to be mounted on the passenger side of the trailer, but it can certainly be mounted on the driver's side as well with some simple modifications. The reason it's designed to install on the passenger side is just for safety, as this provides an easier position on the side of the road if maintenance during a trip is ever needed.

• Where Does Small Pin Install on Reese 5th Wheel Hitch RP30051
• The pin you're talking about looks to be the indicator to let you know when the arm of the Reese 5th Wheel Hitch is in a towing or maneuvering position (see attached photo). You will install the indicator pin in the arm so that it just goes through the bottom side of that arm. In addition to the parts you already have I recommend picking up some in-bed wiring to make your trailer wiring connections easier. This means you'll be using the following parts for your 2017 GMC Sierra 2500 towing...

• How To Install a Battery On a Trailer for Use with Electric Jack
• I have attached a photo for you that shows how a 7-way trailer connector is wired. If you take a look at the trailer side trailer connector you will see a terminal labeled "12V Power". If you were to run a wire part # 10-1-1 (per foot) from this terminal on the 7-way trailer connector to the positive terminal on the battery that would then provide a maintenance charge while the trailer is attached and the vehicle is running or the key is in the ACC position. This will depend on how the...

• What is Gooseneck Trailer Coupler Overhang and Clearance Needed
• In regards to a gooseneck trailer, the coupler overhang is essentially the "neck" of the gooseneck. To make sure you have enough clearance to go over road bumps and make sharp turns, you want to have at least 6 inches between the overhang of your gooseneck trailer and the bed rails of your truck. This is measured from the bottom of the overhang to the top of your truck's bed rails, as shown in the attached photo.

• How to Add Aftermarket Brake Controller to 2015 GMC Sierra 2500 With Factory Brake Controller
• The first thing you will need to do is take your 2015 Sierra 2500 to the dealer and have the computer flashed to disable the factory brake controller. Doing this will remove the risk of the check engine light or other messages displaying on the dash. After this is done, you can install a brake controller like the Redarc Tow-Pro Liberty # RED24FR you looked at using the # 331-TPH-010. Once you plug the controller into the factory port you will be ready to go.

• Can the Erickson Truck Bed Ladder Rack #07708 be Reverse Mounted?
• Although you could physically mount the Erickson Truck Bed Ladder Rack # EM07708 to the outside of your truck, it is not recommended. The reasoning is two fold; the rack installed in that manner puts the weight on the outside of the bed which the foot isn't intended to support by the design (as shown in the attached video) and many states can ticket you for having anything that is past your side mirror to the outside of your vehicle. The telescoping arm width is 19 inches to 34 inches. So,...
