• Can The MaxxAir MaxxFan Deluxe Be Open While Driving
• Yes, due the the unique design of the MaxxFan Deluxe Roof Vent # MA00-07500K it can be left open while travelling. If you don't have the fan running while it's open the powered lift will close so if you plan on just having it open to vent you'll want to leave it off and manually open the vent before hauling your trailer.

• Installation of Brake Controller on a 2011 GMC Sierra With Tow Package
• We have not seen a 2011 GMC Sierra that will have a factory brake controller plug-in for an aftermarket brake controller. All of the 2007 and newer GM full size trucks and SUVs quit offering a plug-in type connection. None of the brake controller harness manufacturers produce a plug and play wiring harness that will fit a 2011 GMC. The plug you are referring to is probably not for the brake controller. If you need to find out what the plug is for you can use a circuit tester, part # PTW2993,...

• How Fast Can I Go On a Snow-Covered Highway Using Tire Chains
• First, if there are posted speed limits, make sure to obey those. We usually recommend traveling no more than 30 to 40 miles per hour with chains installed. The faster you travel the more wear you can put on the chains in addition to a higher chance of losing traction. Pewag and Glacier suggest an even more modest pace of 25 miles an hour or so. I have included a link to our tire chain FAQ article for you with additional information on the use of chains. Be sure to consult your owners...

• How to Adjust CIPA Custom Towing Mirrors on GMC Sierra
• The CIPA Custom Towing Mirrors # CM10800 that you recently installed on your Sierra feature a basic floating design that allows for manual adjustment. I spoke with my contact at CIPA to see if he could provide any tips for this process. He did state that the mirrors are constructed to be free of vibration when driving, so the relatively extensive pressure you are needing to apply to them in order to adjust the mirror is perfectly normal and actually by design. He just recommended applying...

• Fasteners for Install of Erickson E-Track Wheel Chock
• The 2-1/2" Long Torx Trailer Floor and Wall Liner Screw # TFX250ACQ could be used to secure e track wheel chock like the part # EM09160 but it would not be your most ideal solution since this is designed to secure wood to metal. You are wanting to secure metal to wood so using carriage bolts, nuts, and washers will give you the most ideal and secure way to attach the # EM09160.

• No Trailer Connected Error for Prodigy P3 on 2009 GMC Sierra with OEM Brake Controller
• Thank you for all of the details! Since your 2009 GMC Sierra has the factory integrated brake controller you need to run your own 10 Gauge Wire # 10-1-1 from the blue wire on the Prodigy P3 # 90195 back to the brake output pin on your truck 7-Way socket. This is because you have to essentially bypass the wiring for the OEM controller. I recommend using heat shrink butt connectors # DW05745-5 to make your connections.

• Locating Factory Brake Controller Wiring on 2012 GMC Sierra
• Your 2012 GMC Sierra is not equipped with a factory brake controller port for a simple plug-in installation, but all the necessary wires are indeed already run to beneath the dash so that it is just a matter of connecting the 4 wires from the brake controller to the factory wires on the truck. These wires should be on the driver's side in front of the fuse panel to the left of the brake pedal. They will likely be taped to other wiring and you will just need to pull them free. There should...

• How to Remove Broken Step Pad Peg from Barrel Clip on a 2011 GMC Sierra 2500
• You would have to pry apart the barrel clips to get them off of the pegs on the bottom of step pad # 23-0001. You should be able to reuse them though as long as they are not permanently damaged in the process. Barrel clips # 23-0002 will fit the pad you ordered should you need to replace one. Since the pegs broke off in the clips you would have to try to pull them out with needle nose pliers. Otherwise drilling would probably be the best option. But take it slow so as not to damage the...
