  • Can AirLift Air Bags Be Used to Raise/Lower the Rear of a Vehicle for Easier Loading and Unloading?
  • I spoke with AirLift about the Air Lift WirelessONE Compressor System for Air Helper Springs # AL25980EZ and they said that their airbags will work for that, however the amount of height gained would be marginal. They mentioned that typically you are likely to only gain an inch or so over stock height.

  • How to Determine Correct Brackets for Draw-Tite Service Body Trailer Hitch
  • In order to determine the brackets that may work for the Draw-Tite Ultra Frame Service Body Trailer Hitch Cross Tube - Class V - 2" # 41990 (44" wide) you are going to need to measure to determine if you need the 7" Weld-On Bracket Kit # 4907 or 16" Weld-On Bracket Kit # 4916 because this hitch is not designed for one specific vehicle like your Suburban. Simply measure from the top of the frame on your '75 Suburban to the bottom of the bumper. If you need less than 5-9/16" to clear the...

  • How to Use Andersen Ultimate 5th Wheel Hitch on 2019 GMC Sierra Long Bed With Factory Pucks
  • Since the Curt Ball and Safety Chain Loop Kit # C60692 won't allow you to tow a fifth wheel trailer, the best option for your 2019 GMC Sierra 3500 with the factory puck system is the Andersen Ultimate Connection 5th Wheel Trailer Hitch System with Adapter # AM3200. This 5th wheel hitch adapter simply installs onto industry standard base rails, so because your '19 Sierra has the factory 5th wheel prep package you would simple need an adapter that fits in the puck system, the Demco 5th Wheel...

  • Can the Factory Brake Controller be Bypassed on a 2007 GMC Sierra New Body Style
  • Yes, you can bypass the factory brake controller on your 2007 GMC Sierra new body style. You will need to add enough 10 gauge blue wire, # 10-1-1, to reach from the cab of the truck to the 7-Way at the rear of the truck. It is sold in 1 foot increments so a quantity of 1 would be 1 foot. I would recommend at least 20 feet. I have included a link to a help article that explains the process of bypassing the factory controller for you. For a brake controller I recommend the P2 # 90885 because...

  • Installation Instructions for Putco Grille on 2014 GMC Sierra 1500
  • I spoke with my contact at Putco regarding the Punch Grille Insert, part # P84194, which you reference, and he said after removing the factory plastic hood that covers the area between grille and radiator like you have done, you will place the insert over the grille. Then place a bolt through the pre-cut mounting holes and place the mounting bracket on the back so it attaches to the grille and tighten with allen wrench. Then reinstall the hood cover and you will be good to go. Check out...

  • Effective Tongue Weight Range for Reese RP66560 Steadi Flex Weight Distriubtion System
  • The spring bars used on weight distribution systems like the Reese # RP66560 Steadi Flex are rated for a certain range of trailer tongue weights. The bars included with the # RP66560 are rated between 600-1200 lbs and would work perfectly for any tongue weight within that range. Adjustment isn't possible or necessary. You'll also need a trailer ball with a 1-1/4 inch shank. For a 2 inch ball, use # A-90 or for a 2-5/16 inch ball use # 19286. I've linked you to a video that explains...

  • Brake Controller Installation on a 2012 GMC Sierra 1500
  • It sounds like you are on the right track. Your 2012 GMC Sierra does not have an OEM plug for installing a brake controller, but they did run the wires for you. We do not offer an adapter that would allow you to hard wire the Hayes Energizer III brake controller, but you do have the option of just cutting off the existing plug. You should be finding the correct group of wires under the left side of the instrument panel you see to the left of the steering column. There may very well...

  • Is 2020 Jayco Eagle 347BHOK Prepped for Side Cameras on Furrion Vision S Camera System
  • I personally think the 3-camera systems from Furrion, like the Furrion Vision S Wireless RV Backup Camera System # FCE48TASL-05, are one of the best options out there because they give you a better view of your surroundings. When installing the side cameras you will need to wire them to the running light circuit as well as the turn signals, so the side camera installation won't be as cut and dry as the rear camera. The running light circuit will give them power while the turn signals not...

  • What Batteries Will the TorkLift PowerArmor Box with Solar Charger # TLA7700LS Charge
  • The TorkLift PowerArmor Solar Locking Battery Box - 6 and 12V Lithium Batteries - Powder Coated Aluminum # TLA7700LS will charge lead acid batteries, AGM batteries and deep cycle batteries. I spoke to my contact at TorkLift and confirmed it will keep 2 batteries charged. He also said the TorkLift PowerArmor Solar Locking Battery Box is a trickle charger, meaning it will maintain the charge but it won't really add to the charge, unless left on for a long period of time.

  • Can Timbren Silent Ride Systems be Used in Ruts
  • The Timbren Silent Ride systems like the part # TSR14K35T01 that you referenced weren't tested for the exact situation you mentioned so it's hard to say exactly what would happen. Timbren intended this setup for on-road applications but if you found yourself in a situation where the tires were in ruts you'd want to pull straight out of them to prevent any twisting.

  • Should There Be a Light On the Redarc Tow-Pro Liberty Brake Controller While Driving Without Trailer
  • In regards to the Redarc Tow-Pro Liberty Brake Controller part # # RED24FR, the unit should not be illuminated while driving without a trailer. If you press the button while a trailer is not attached you should see a breathing blue light and that simply indicates the controller is in sleep mode.

  • Slide Out Awning for 80-3/4 Inch Slide for 2019 Aura Trail Lite 22RF
  • Thanks for the photo and you are right about the fit for the 80-3/4 inch slide on your 2019 Aura Trail Lite 22RF; the correct one is the Solera RV Slide-Out Awning # LCV000163287. The exterior framing piece is not something I believe is going to be an issue for the install. The brackets should go inside and under that framing piece, and it doesn't look as if it extrudes outward so that it will interfere, so I don't foresee any issue at all. In regards to the awning rail, you just want...

  • Is There an Easier Way to Set 2019 GMC Acadia to Flat Tow Mode
  • The FuseMaster Bypass Switches # RM-76517 and # RM76511 can be used to help make prepping your 2019 GMC Acadia for flat towing easier, but when it comes to the standard procedures for setting up your Acadia put in place by the manufacturer there isn't really a way to get by that and make it any easier. Since flat towing is different than every day functions of vehicles the manufacturers usually make it a little more tricky to get into flat tow mode so that this doesn't happen on accident.
