Expert Answers about Grand Design


  • Can I Use One Large Storage Bin LC175725 With The Underchassis Double Bin LC175180
  • Good question. The Large Storage Bins # LC175725 and the Small Storage Bins # LC131633 do have the same dimensions as far as height and width, so technically the Underchassis Double Bin # LC175180 could accommodate one of the larger bins. My only concern is that the Underchassis Double Bin # LC175180 has a metal tube attached to the frame which is kind of a stopper for the small bins (see picture below). This metal piece would prevent the larger bin from sliding in all the way and would...

  • How to Find the Correct Replacement Leaf Springs for a 2022 Grand Design 265BH
  • Hey Eric, the 6-Leaf Double-Eye Spring for 5,300-lb Trailer Axles # SP-222275 could work but really to be sure you'd need to measure the length from center of spring eye to center of spring eye (unloaded), measure the leaf thickness, and find out what capacity your current leaf springs are. If your current leaf springs are 24 7/8 from spring eye center to spring eye center (unloaded), have 1 3/4" wide leaves, and have a spring capacity of 2,650 lbs, then these'll work great. If not,...

  • Replacement 205/75R15 Trailer Tires For a Tandem Axle Trailer With 3,500LB Axles
  • The Load Range D # AM10245 205/75R15 is going to be more capacity than you need for your camper using 3,500lb tandem axles. Each tire is rated to support up to 2,150lbs which would be 4,300lbs for the axle. A better option would be to use a Load Range C # AM10244 which is rated for 1,820lbs per tire. This would be 3,640lbs per axle which is much closer to the maximum capacity of each axle. With that your tires will flex more than bounce like you get with the higher capacity tire.

  • Replacement Trim Needed for Underside Panel on a 2019 Grand Design Momentum 5th Wheel Toy Hauler
  • Hey Kyle! We have a variety of trim pieces for trailers (see attached link) but since the design will vary from trailer to trailer I'll need some dimensions and possibly some photos to see if anything we carry matches what you're needing to replace.

  • Recommended Upgraded Equalizers For A 2021 Grand Design Transcend Xplor Travel Trailer
  • Hey James, If you have standard equalizers with a 5-3/4" horizontal and 2" vertical measurement then the Dexter E-Z Flex Suspension Kit # K71-652-00 would be the correct replacement for you. If you're saying that you already have those and are wanting something else then you can go with the Equa-Flex Cushioned Equalizers # LC279687. These have a 5-1/2" horizonal and 2-1/2" vertical measurement so you'll probably have enough slack in the shackle straps to accommodate this difference without...

  • Replacement Upgraded Leaf Springs for 2018 Grand Design Imagine 2800BH
  • If what you have now Chad is pretty flat at 26 inches then the best replacement size would be 25-1/4 inches like you mentioned. Since you wanted to increase the capacity you would want the part # e57SR which is for 4k trailer axles.

  • Will 225/75R15 Tires Fit on a 2018 Grand Design Imagine 2500RL Travel Trailer?
  • I do see both the load range D Westlake ST205/75R15 Radial Trailer Tire # LHWL300 and load range E Westlake ST225/75R15 Radial Trailer Tire # LHWL304 are both designed to fit a 15x5 or 15x6 wheel. So as long as your 2018 Grand Design Imagine 2500RL travel trailer has enough clearance for the larger tire size you should not have any issues. The 225/75R15 is 1.2" taller and 0.8" wider than your current tire. It is recommended to have 1" of sidewall clearance and 3" of vertical tire clearance...

  • Determining if MORryde StepAbove Will Fit 2020 Grand Design 351 Momentum
  • Hey Samantha we can definitely help you determine if the MORryde StepAbove STP -213 part # MR28RR can fit your 2020 Grand Design 351 Momentum but we don't have the fit confirmed because we aren't sure of what the door dimensions are. So what you need to do is just basically take a couple dimensions and you'll be good. As long as your door's threshold is between 36-1/2 inches to 42 inches from the ground and is between 27-3/4" - 30-1/4" in width from within the threshold these will fit....

  • Will MORryde Pin Box MR84VR Give Extra Clearance Replacing Lippert 1621HD
  • The dimensions of the Lippert 1621HD are going to be the same as the MORryde Cushioned 5th Wheel Pin Box # MR84VR so you won't get any type of added clearance. The only way you can get added clearance is by replacing your pin box with the Reese Sidewinder # RP34FR.
