• Will the Factory Brake Controller On a 2009 GMC Sierra 2500 Work With a Dexter DX EOH
• The factory brake controller on a 2009 GMC Sierra 2500 is NOT compatible with an electric over hydraulic brake actuator as is. It sounds like you are aware of an adapter for this but these are only available for HydraStar and Titan Electric Over Hydraulic Brake Actuators, not Dexter. Therefore, you really only have one option which is to obtain a new aftermarket brake controller. For an aftermarket brake controller, you could use the Tekonsha Prodigy P2 Trailer Brake Controller part #...

• How to Extend Trailer Connector to Mount on Aftermarket Bumper
• I do have a solution to extend your 7 way to reach your new bumper, the Tow Ready Replacement 7 way Harness and Socket part # 20147. It provides you with an additional 17" of wire, and a US car connector to plug into the back of the seven way connector. You will cut the existing connector off your truck, and crimp the new harness on with the included butt connectors, then plug the connector into the back of the plug. If you need a new socket also, I recommend the 7-Pole and 4-Pole Trailer...

• Is It Okay To Use the Reese 12K Steadi-Flex On a Trailer Under 12K
• Yes, you can use a weight distribution system that is overrated for the trailer you intend to use it with. However, the best performance will come from a system that matches the total tongue weight of your towing setup. In order to find the total tongue weight of your towing setup you will need to calculate the loaded ready to tow tongue weight of the trailer plus the weight of any cargo stored behind the rear axle of the tow vehicle. The Reese Steadi-Flex Weight Distribution System part...

• Which Slider Hitch is Better the B and W Patriot Slider or the Curt A20 Hitch
• B and W are widely considered to make the best designed fifth wheel hitches out there. They are made in the USA, very reliable, not known to wear out, easy to use, and the quietest option as well. I would go with the Patriot slider # BWRVK3270 over this one though. I attached a review video for this hitch for you to check out as well.

• 2005 GMC Sierra Firestone Ride Rite Air Bag Kit Options
• If you're needing all of the brackets then it's actually more cost-effective to get a whole new kit than to get the brackets for your 2005 GMC Sierra. I've actually looked into this a number of times (hoping that it changes) and I've reached out to Firestone a handful of times as well and unless you're only replacing a few brackets you'll save money with a new kit (plus I'm not sure I would trust the integrity of any of the brackets on a totaled truck). For a new Ride-Rite kit we have the...

• Selecting Weight Distribution for StarCraft Antigua 255 RQB Travel Trailer Towed by 2008 GMC Sierra
• Selection of a properly-tuned weight distribution (WD) system requires you to know your trailer's fully-loaded and ready-to-tow tongue weight (TW) with all your usual gear and supplies loaded. To this measured TW you need to add the weight of anything in the Sierra that sits behind the rear axle, such as a generator or loaded cooler. The linked article explains how to measure TW. These two weights added together give you your total tongue weight (TTW) and that is the key for choosing the...
