Expert Answers about Grand Design Momentum 5W Toy Hauler


  • Trailer Hitch Receiver For a 2018 Grand Design Momentum 376TH 5th Wheel Toy Hauler
  • It would appear the Curt Adjustable Width Trailer Hitch Receiver # 13703 is going to be the best option for your 2018 Grand Design Momentum 376TH 5th Wheel Toy Hauler. This receiver will fit frame widths 22" to 72" wide and is rated for a tongue weight of 350lbs with a maximum trailer weight of 3,500lbs. We have not had your Momentum inside our facility to measure the frame and verify this is going to fit without any modification but the mounting plate will allow it to hang down lower so...

  • Lippert Trailair Flex Air 5th Wheel Pin Box For a 2022 Grand Design Momentum 395MS Toy Hauler
  • The information I found says that your 2022 Grand Design Momentum 395MS 5th Wheel Toy Hauler has a 1621HD pin box. That would make the Trailair Flex Air 5th Wheel Pin Box # LC369535 the correct pin box for you. A Portable Air Compressor # BDW41002 is good to keep with the 5th wheel so that you can make adjustments to the air bag when needed so the pin box rides at the correct height.

  • Could Hopkins 7-Way Cigarette Lighter Adapter be Used to Power Ultra Fab A-Frame Power Jack
  • Yes, you could use the Hopkins Cigarette adapter part # HM47675 when powering the Ultra-Fab Electric A-Frame Jack # UF38-944017 as long as you were able to run the wires of the jack to a cigarette lighter type adapter. It would then just plug into the Hopkins and be ready to use.

  • Can The Everchill RV Mini Refrigerator Be Used In A Lower Storage Compartment Of A 5th Wheel
  • Yes, the Everchill RV Mini Refrigerator w/ Freezer # 324-000110 can be placed in the "basement" storage compartment of your 5th wheel. My father has the same fridge in a lower compartment of his Jayco 5th wheel that is just deep enough for the fridge and has about a foot of space to the side.

  • Equalizer Upgrade Fit For 2018 Grand Design Momentum 350M
  • So the issue isn't going to be the shackle strap length as getting straps that are less than an inch longer won't make up the difference you are seeing. The issue is that the Road Armor Shock Absorbing Equalizer Kit # LC696740 you have is the wrong size to replace the equalizers on your 2018 Grand Design Momentum 350M. I was able to check with Grand Design and find the equalizers that fit your rig, which are the Equa-Flex: - Equa-Flex Cushioned Equalizers # LC279688 I added a photo showing...

  • How to Get Smoother Ride For 2017 Grand Design Momentum 399TH That Won't Raise Trailer
  • While we do have an option for you to get a smoother, more comfortable ride for your 2017 Grand Design Momentum 399TH, the Center Point # LC1565401 is going to raise your trailer by 2 inches, and there isn't any alternative method of install or anything that won't affect your ride height. So instead, what I recommend are shock absorbers from Roadmaster: - Roadmaster Comfort Ride Shock Absorbers for Triple Axle Trailers # RM-2460-3 These are the right size for your triple-axle '17 399TH,...

  • Converting From Drum to Disc Brakes On a 2020 Grand Design Momentum with 7K Axles
  • In order to convert the electric drum brakes on a 2020 Grand Design Momentum to hydraulic disc you can indeed use the Kodiak Disc Brake Kit part # K2HR79 which have oil bath lubrication. That said, you will need a list of other components which I have attached for you. Disc Brakes: part # K2HR79 (1 Per Axle) Inner Bearing: part # 25580 (2 Per Axle) Outer Bearing: part # 02475 (2 Per Axle) Seal: part # 9103309 (2 Per Axle) Brake Actuator and Lines: part # CAR-HBA16-2 (1) part # 9579-01...

  • TorkLift Step Compatibility with 2018 Grand design Momentum 328m
  • The TorkLift GlowStep Revolution Scissor Steps w/ Landing Gear - 4 Steps - 27-1/2" Base - 375 lbs # TLA8004 are a fit for your 2018 Grand Design Momentum 328M. They can be used to replace your current steps if desired. If you have factory SolidSteps then you likely will need to cut a portion of your siding to accommodate the mounting bracket for these steps and will also need the outrigger brackets # LC301704. If you want a step that doesn't require cutting but also will stick out from...

  • Depth Needed To Install Lippert SolidSteps In A 2016 Grand Design Momentum
  • The SolidStep Manual Fold-Down Steps # LC791575 are approximately 9" in depth from the threshold stop to the edge of the steps (pictured below). You'll need to measure from the doorstop in the center of your threshold out and see just how much space you have between it and the steps to know if these will fit.

  • Recommended Furrion Tankless Water Heater Door Size For A 2021 Grand Design Momentum 376THS
  • The access doors from Furrion are 1/8" larger than their dimensions so the 16" x 16" would really be 16-1/8" x 16-1/8". If the height is less than 16" and the width is just over 16" then I recommend the Furrion RV Tankless Water Heater # FR48SR. If the height is 16" or larger then I recommend going with the 18" x 18" # FR98SR. To complete your installation you'll also want to put some butyl tape on the mounting flanges for both the main unit and access door. You'll also want some non-sag...

  • Recommended RV Storage Cover For A 2021 Grand Design Momentum 376THS
  • The Best fit for your 2021 Grand Design Momentum 376THS is going to be the Adco Olefin HD All-Climate + Wind RV Cover for 5th Wheel Toy Hauler - Up to 43' Long - Gray # AD89ZR. The Olefin HD travel trailer cover works best for long-term storage in all climates. They are not waterproof because a waterproof cover would prevent moisture from escaping causing mildew, mold, and rust. Instead, ADCO makes their covers highly water-resistant so that water beads off. They also build vents into each...

  • Recommended Base Rails For A 2005 Chevy Silverado 3500 Dually With A Husky 24k Hitch
  • It sounds to me like you possibly had some non-ISR rails in your bed and that were only compatible with that 16k Husky hitch that the previous owner had. You're going to want to first confirm that your hitch will fit ISR (Industry Standard Rails) and then swap out your base rails to safely tow your trailer and end any doubt about safety. If your hitch is compatible with ISR rails then I recommend the B&W Custom Installation Kit w/ Base Rails for 5th Wheel Trailer Hitches # BWRVK2500....

  • Is It Better To Replace The Brake Shoes Or Completely Replace The Brake Assembly
  • Most people prefer to completely replace the brake assembly instead of replacing just the brake shoe because the cost of the brake shoes is about 3/4 the cost of completely replacing the assembly and you'll typically have quite a hard time removing and swapping in the new brake shoes, especially if you don't have the correct tools and have the technique down. It's much easier to just pop the brake assembly off of the brake flange and swap in a new # AKEBRK-7-SA, which will give you all...

  • Recommended Pin Box For A 2022 Grand Design Momentum 351MS With A Lippert Rhino Box
  • The Rhinobox was definitely an unpopular choice for manufacturers to go with so swapping it out with the MORryde Cushioned 5th Wheel Pin Box for 18K to 21K Trailers w/ Lippert Rhino # MR55QR would definitely give you a major improvement in ride quality. That being said, a 2022 Grand Design Momentum 351MS has a GVWR of 16,800lbs so you would want to use the MORryde Cushioned 5th Wheel Pin Box for 14K to 18K Trailers w/ Lippert Rhino # MR83QR instead. The internal spring for this pin box...

  • Do Brands Matter When Installing Accumulator Tanks And Can Multiple Be Used Together
  • Brands don't matter when it comes to installing the Seaflo Accumulator Tank for RV and Boat Water Pumps # SE38FR or any other accumulator tank. You could install multiple accumulators but you wouldn't really see a benefit from it unless you moved them closer inline to the point of use (shower, faucet, etc.).

  • Reese Goose Box For a 2017 Grand Design Momentum 350M 5TH Wheel Toy Hauler
  • Since you have the MORryde Cushioned 5th Wheel Pin Box # MR84VR (RPB72-1621HD) on your 2017 Grand Design Momentum 350M you will need the Reese Goose Box 5th-Wheel-to-Gooseneck Air Ride Coupler Adapter # RP85FR as it has the same 1621 bolt pattern. You will also need the Reese Safety Chain Kit # RP49151 as you are going to a ball type connection and any ball connection will require safety chains.
