Expert Answers about Grand Design Momentum G-Class 5W Toy Hauler


  • Will Fan-Tastic Vent Roof Vent Cover FVU1500WH Fit Fan-Tastic Vent On 2020 Grand Design Toy Hauler
  • The Fan-Tastic Vent Ultra Breeze Trailer Roof Vent Cover - 23" x 19.5" x 10.25" - White # FVU1500WH you were looking at will work with your Fan-Tastic vent on your 2020 Grand Design Momentum G-Class 5th Wheel Toy Hauler as it is confirmed to fit all Fan-Tastic vents, but without seeing the current mounting brackets I am unable to confirm if the brackets will be correct. If they are not you can remove them and use the brackets included with the # FVU1500WH. I also recommend using LaSalle...

  • Traction Material for Inside of Ramp Door on Toy Hauler
  • Other than the grip tape such as # PT24ZR or # PT57ZR we do offer an alternative that might work for you. I'd recommend using a rubber utility mat like part # DZ85009, which measures 6 feet by 3-1/2 feet wide. You might need to trim the mat to meet your needs, but this seems like a good solution. I'd recommend using contact cement to attach it to the inside surface of the ramp. Depending on what the inside surface of the ramp is and how the grit is applied, it might be possible to remove...

  • Step Options for a Back Deck/Patio on a 2022 Momentum Grand Design 28G Toy Hauler
  • I do have a couple potential options for you, but we do not have any steps with a long platform on top to lay down on the deck of your 2022 Momentum Grand Design 28G toy hauler. We have the Econo Porch Trailer Step with Handrail and Landing # EHS-102-R. This is a step style that will not require you to attach anything to the deck. This can be folded up for storage, but does require that you remove some screws to get the braces off for storage. The other option are the Victory Step Manual...

  • How to Pick Out Replacement MORryde Suspension Upgrade for EquaFlexon 2019 Grand Design 381M
  • It really comes down to knowing what Equaflex you have now or the dimensions of them and then picking out the matching MORryde kit. The part # MR87ZR is made to fit the most common dimensions as it is for 33 inch wheelbases and has 6-1/2 inches between the front and rear bolt holes with 3-1/8 inches between the holes vertically.

  • Replacing the Lippert 1621HD with a Trailair Flex Air 5th Wheel Pin Box
  • Yes, the Flex Air 5th Wheel Pin Box, # LC328492 is a replacement for the Lippert 1621 rated18,000 lbs. and will match the bolt pattern to replace a Lippert 1621HD. However, I suggest you compare this to the weight rating of your trailer and if you need more than 18K, I recommend you select the Curt Air Ride 5th Wheel Pin Box, # LC158778 as is listed for the Lippert 1621HD being rated for 21K.

  • Recommended SumoSprings For 2019 Grand Design Momentum 354M W/ Tandem Overslung 7000lb Axles
  • I would be happy to help! Since the SumoSprings Trailer Helper Springs w/ Line Relocation Bracket - Single Axle - 3K to 5K - Overslung # TSS-107-40 you were looking at are only rated for 3000-5000lb axles and your Grand Design Momentum 354M has tandem 7000lb axles you will want to go with the SumoSprings Trailer Helper Springs w/ Line Relocation Bracket - Single Axle - 5K to 8K - Overslung # SS26MV. The # SS26MV are designed for trailers with 5000-8000lb axles that have axles underneath...

  • Upgrading Equalizers and Cushioned Suspension Hangers for 2022 Grand Design Momentum 25G
  • I will need to know more info to pick out those components. To pick out replacement leaf springs I would need to know the length of your current springs so that I can match that with what we carry and I would need to know the width and height of your current equalizers. You should note that in the 7k and 8k axle springs we only have options that are 24-7/8 inches long like the part # DX74XR for the 8k springs and part # e64SR for 7k. Now if the wheelbase of your RV is 35 inches you'd...
