  • Troubleshooting A Nose High Trailer To Install A Roadmaster Comfort Ride Suspension System
  • If your trailer is so nose high that you can't use a Roadmaster Comfort Ride Suspension system then you shouldn't be towing it as it is currently. There are multiple ways to fix your ride height issue: Start by adjusting the hitch head height down, while still maintaining a 6" space between the nose of the trailer and the top of the truck bedrails. If this isn't an option then you can look into alternative hitches that have a lower height setting. If you want me to look for some I'd just...

  • Can A Roadmaster Comfort Ride Suspension Be Installed A Trailer That Rides Slightly Nose High
  • Yes, you can still install the Roadmaster Comfort Ride Leaf Spring Suspension Kit even though the trailer rides slightly nose high when coupled to the tow vehicle. When installing one of these kits you'll most likely need to get longer U-bolts since there typically aren't enough threads to accommodate the additional mounting brackets. To determine the right kit and U-bolts you'll need to know the capacity and diameter of your axles and how many axles your trailer has. 3.5k 2-3/8" Tandem...

  • Will Ford TPMS for Trailers Work with 17-1/2 Trailer Wheels
  • I do have an option for you but the Ford TPMS for Trailers only works with 15" and smaller trailer wheels due to the valve stem hole size of .452" they use. The valve stem hole size on a 16" and larger trailer wheel like the Westlake 215/75R17.5 Radial Tire w 17-1/2" Lynx Aluminum Wheel # LHAS701 will be .625". Therefore, in order to run TPMS on larger wheels you'll need an aftermarket system like the Tuson Towable Tire Pressure Monitoring System part # 335TPMS6WIVS.

  • How To Choose Correct Replacement Leaf Springs for a 5th Wheel Trailer
  • In order to find the correct leaf springs for a trailer you need to know their type (slipper/double eye), axle capacity, and unloaded length. I have attached a full list of options below. The 6-Leaf Double-Eye Spring part # e64SR for example has double eyes, a 7,000 lb capacity, and 24-7/8" unloaded length. Unfortunately, we don't have any way to look up parts for any given trailer.

  • Is The Furrion Vision S Wireless RV Observation Camera Compatible With A 2018 Chevrolet Silverado

The issue with the Furrion Vision S Wireless RV Observation Camera System w/ Side Marker Light Cameras # FCE48TASL-05 and the newer (2019-Current) GM vehicles has to do with the trailer lighting circuit not providing enough power to power the cameras.

  • Will Weight Distribution System Fix Trailer Sway on 2017 Grand Design Imagine 3150BH
  • Persistent trailer sway actually does not get fixed with a weight distribution system as a WD system can only minimize sway from passing semi trucks or high winds. If you are experiencing a sway that starts at a certain speed and basically doesn't stop till you slow down the issue is most likely not enough tongue weight in your trailer. You need 10-15 percent of the total trailer weight as tongue weight and to have the trailer sitting as level as possible for the sway to stop. Sometimes...

  • Lippert Shocks or SumoSprings For 2023 Grand Design Reflection 367BHS 5th Wheel Trailer
  • The better ride quality for your 2023 Grand Design Reflection 367BHS will definitely be the shock kit from Lippert: - Lippert Bolt-On Shock Kit w/ Heavy Duty Gas Shocks - 5,200-lb to 7,000-lb (3") Overslung Axle # LC281281 While the SumoSprings # SS26MV help with stability, they are denser and less forgiving, so the ride will be rougher when compared to the gas shocks of the Lippert kit. These shocks will do a better job of providing a smoother ride while still offering stability.

  • What Can Be Used To Prevent Theft of The Equal-i-zer Weight Distribution System # EQ37140ET?
  • With the design and removable parts of the Equal-i-zer Weight Distribution System # EQ37140ET the only real option you have for securing it is the Locking Hitch Pin # e98881. This will lock the hitch into the receiver. When connected and the weight on the spring bars it is not the easiest hitch to remove quickly.

  • Will The MORryde Scissor Jack Cross Brace Work On A 2023 Grand Design Solitude 380FL 5th Wheel
  • If the scissor jacks on your 2023 Grand Design Solitude 380FL 5th Wheel are oriented with the open ends facing the front and back of the trailer (as seen in the picture below) then you'll be able to use the MORryde Scissor Jack Cross Brace Stabilizer for Trailers and RVs # MR82AR. These cross braces will utilize the existing hardware on your scissor jacks for installation. If the hardware is too small you may need to drill out the hole on the jacks and enlarge it to fit the correct sized...

  • Roadmaster Comfort Ride Shock Absorber Fit For 2021 Grand Design Imagine XLS 21BHE Travel Trailer
  • While there is a Comfort Ride shock absorber kit that does fit your 2021 Grand Design Imagine XLS 21BHE, there is not a leaf spring suspension kit, as those are only fits for axles larger than the 3,500 lb tandem axles on your travel trailer. You will still get a much improved ride with the shock absorbers, with the correct fit for your trailer being the following: - Roadmaster Comfort Ride Shock Absorbers for Tandem Axle Trailers - 3,500 lb Axle # RM-2450 The Comfort Ride # RM-2450 will...

  • Does The Lippert Solid Stance RV Step Support Work With The Lippert Tread Lite Steps?
  • Since your Lippert Electric Tread Lite Step for RVs # LC353543 is made of aluminum, the Lippert Solid Stance RV Step Support # LC96BJ will not work for you, unfortunately. instead, you'd need steps made of steel like the Lippert Manual Pull-Out Step for RVs # LC432687. You will also need at least 5" of ground clearance to ensure you have a proper fit. I have attached a couple videos for you to check out as well.

  • Upgrading Suspension System on 2018 Grand Design Imagine Travel Trailer
  • For your 2018 Grand Design Imagine 2600RB you will need to measure the axle spacing by finding 2 common points on your axles to measure between. Generally this is done by measuring from center of one axle to the center of the 2nd axle. I never like this as they are difficult to get an accurate measurement. I prefer to measure from the u-bolts front to rear axle or the tires as long as they both have even wear. Since you are looking to replace the equalizer I recommend measuring the equalizer...

  • Can 1157 Incandescent Bulbs In a Trailer Tail Light Be Replaced With LEDs
  • In general, yes, most incandescent bulbs can be swapped out for an LED. In order to do this you need to know the bulb type such as 1157. That said, when replacing incandescents with LEDs you must use the same color bulb as the lens in order for the light to show through properly. For example, if you were replacing a tail light bulb behind a red lens then you would need to use part # ARC63FR.

  • Furrion Tankless Water Heater to Replace Dometic
  • Each of the Furrion tankless water heaters measure 12-5/8" wide x 12-5/8" tall x 19-1/4" deep, so that is the size the compartment needs to be. As for the door, there may be trimming needed, depending on the size of the door you have now and the heater you get. Generally some type of trimming is needed as the doors on different models aren't universal sizes. So you need to measure your current door size and go with the Furrion heater that has the closest dimensions. - 16" x 16" Door: Furrion...
