  • Weight Distribution Recommendation for Cadillac Escalade that Needs 8 inch Drop
  • For a weight distribution system that would work great for your 2016 Cadillac Escalade that needs an 8 inch drop the Strait Line part # RP66072 would work great as it does not come with a shank and you can then use a shank like the part # C17124 that can give you the drop you need.

  • Solar Power System for Going Off-Grid
  • There isn't a particularly simple answer for a solar powered system to go off-grid, because it is totally dependent on how much power you will use per day. I have added a link to a help article entitled "How Much Solar Power Do I Need" that I recommend checking out. It depends on how many amp-hours you use per day and how big your battery bank is. For example if you used more than 150 amp-hours per day a great kit would be the Go Power Solar Flex Charging System with MPPT Solar Controller...

  • Recommended Towing Mirrors for 2018 GMC Yukon XL
  • As long as your 2018 GMC Yukon XL doesn't have the telescoping mirrors I recommend the K-Source Snap & Zap, part # KS80920, because they're ridiculously easy to put on. They fit right onto your factory mirrors and keep the puddle lamps and folding features if you already have them. They're also easy to install with no hardware or tools. I've linked a video from when we installed them on a 2017 Tahoe that has similar mirrors to your GMC.

  • Suspension Enhancement for a 2002 GMC Yukon XL
  • Suspension enhancement products such as the SumoSprings # CSS-1168R are designed to be used with a stock suspension that is in good working order. It sounds like the rear suspension on your 2002 GMC Yukon XL is starting to fatigue some, hence the greater than normal squat, and it would be a good idea to inspect the suspension and replace worn parts as needed. At that time it would be up to you to add stronger springs or suspension enhancement. Please note that adding stronger springs is...

  • Tekonsha Brake Controller Installation Harness Recommendation for a 2001 GMC Yukon XL
  • For your 2001 GMC Yukon XL the correct brake controller harness would be the brake controller harness part # 3025-P. However, the # 3015-P harness that you referenced could be modified to work for you. It would require you moving the red wire to the opposite corner of the connector. You will need to press up on the release tab of the connector that holds the pin to the connector and the wire will pull out from the back of the connector. All you would need to do is insert it into the back...

  • Weight Distribution and Sway Control Recommendation for a 2004 GMC Yukon XL and 7,000 lb Trailer
  • First, you would benefit from using weight distribution and sway control. Weight distribution should be used any time the trailer weighs at least 50 percent of the vehicle. Sway control will be very useful since the trailer is so heavy. If that trailer starts to sway it would make it difficult to keep the Yukon and trailer straight. Regarding a different trailer hitch, the hitch on your 2004 GMC Yukon XL has the capacity to tow your trailer when loaded and ready to tow if you are at the...

  • Swagman XP vs. Swagman Trailhead Bike Rack Comparison
  • I would recommend the Swagman Trailhead part # S63380 for you because this rack has two arms instead of one like the Swagman XP # S64940 which will make carrying bikes easier and more stable. The Trailhead also has anti-sway cradles designed to prevent the bikes from moving around in the rack which will help prevent them from contacting each other. I attached a review video for both racks for you to check out as well. Both racks are confirmed to work at the back of an RV. If you plan...

  • Brake Controller Install Harness Recommendation for 2006 GMC Yukon XL
  • The correct brake controller install harness your 2006 GMC Yukon XL needs is the part # 3015-S. This comes with the connector that plugs in under your dash and the other end has 4 blunt cut wires that you'll match color for color to the wires on your brake controller. I attached a picture that shows which port to plug it into under your dash too.

  • Weight Distribution Recommendation for a Heartland Wilderness Trailer Towed by 2012 Yukon Denali XL
  • The Fastway e2 Weight Distribution System, # FA92-00-1000, should work well with your Heartland Wilderness 3150 DS trailer. The key to choosing the correct weight distribution system is to choose a system that can support to total tongue weight of your towing setup. The total tongue weight will include the loaded and ready to tow tongue weight of your trailer plus the weight of any cargo loaded behind the rear axle of your tow vehicle. I would not expect the total tongue weight of your...

  • Bike Rack Recommendation for the Back of a 2014 Forest River Travel Trailer
  • The weight capacity of the bumper should be included with the literature for the trailer. If not, contact Forest River because that might be something that they know even if not listed in the manual. The Swagman rack # S64663 weighs around 35 pounds or so and when loaded to its max capacity you are looking at a total of 115 pounds. If the bumper is not strong enough or there is not enough space for the rack then I would go with a ladder mounted rack. We have # LA-102 which has a capacity...

  • Weight Distribution for a 2000 GMC Yukon XL Towing a 3,500 Pound Trailer
  • SUVs such as your 2000 GMC Yukon XL tend to have a softer rear suspension than trucks for the comfort of passengers. It doesn't take much to compress that suspension so you could experience some squat at the back. The general rule with weight distribution is that if the trailer when loaded and ready to tow weighs at least 50 percent of the vehicle weight then it is a good idea to use weight distribution. The curb weight of a 2000 Yukon XL is in the neighborhood of 4,700 pounds to 5,200...

  • Programmer Recommendation for 2002 GMC Yukon 1500 5.3 liter
  • A programmer is exactly what you are looking for like the Superchips F5 part # SU2845 that fits your 2002 GMC Yukon XL. This will give you an additional 18 horsepower and 17 foot lbs of torque which will allow your vehicle to tow your trailer without as much down shifting due to the additional torque. It will also give you better fuel mileage when you are towing and when you aren't towing as well.

  • What Size Breaker Does The Roadmaster Battery Charge Line For Towed Vehicle RM-156-25 Use?
  • The Roadmaster Battery Charge Line Kit for Towed Vehicles # RM-156-25 you were looking at uses a 15 amp circuit breaker to keep from over loading the 14 gauge wire. You would not want to wire the # RM-156-25 to the battery disconnect you have, as that would mean your battery would NOT be getting charged so you will want it to bypass your battery disconnect. This kit will require that you have a charge line kit installed on your motorhome. If you do not then I recommend adding the Roadmaster...

  • What are Differences between Roadmaster Sterling and Blackhawk Tow Bars
  • The Blackhawk tow bar part # RM-422 and the Sterling part # RM-576 are both really great options but they have some distinct differences. One being the Blackhawk has a 10k capacity and the Sterling 8k. Both are well above what you'd need so that's not something I'd use to make your decision. The Sterling comes with safety cables which is partially why is costs more, but the really big feature it has over the Blackhawk is the non binding arm mechanism. It has levers that easily pull up to...

  • Can Timbren Suspension Enhancement Fit 2003 GMC Yukon XL with Factory Air Ride
  • The Timbren Jounce Springs # TGMRG25C are a fit for the 2003 GMC Yukon 1500 XL with Air Ride as long as it is the 4-wheel-drive version. These bolt on without drilling in place of the factory bump-stops. They work independently and offer progressive resistance as the load on them increases. I linked an install video for you. If you have the 2-wheel-drive version then instead you'll use part # TGMRYS4.

  • Making Wiring Connections Under the Hood of 2007 GMC Yukon to Make Tow Package Functional
  • The previous owner of your 2007 GMC Yukon probably did not know about the under the hood connections that needed to be made in order for the factory tow package wiring to be fully functional. You can leave it as is but for a cleaner and more professional install I recommend doing it the more correct way; that is to say using the factory wiring as it was intended. I have included a link to a help article that explains this process for you.

  • Which Snow Tire Chains Should I Use On My 2008 GMC Yukon XL That Has 165/70R17 Tires?
  • The reason you did not see the 265/70R17 tire size is because it likely is not as common as the tire sizes listed for your 2008 GMC Yukon XL. For your 265/70R17 tires you can use pewag Brenta-C 4X4 Snow Tire Chains - Square Link - 1 Pair # PWXMR82V. This is a really nice tire chain setup that has a built-in chain tensioner, so you will not have to buy a separate tensioner. It offers a really simple installation process which you can see in the video I attached for you. Keep in mind these...
