Expert Answers about Grand Design Reflection Fifth Wheel


  • Replacement brake Assemblies For A 2015 Grand Design 337RLS
  • Hello Richard, thanks for reaching out. Your 2015 Grand Design 337 RLS uses two 7,000 lb axles. This means the brake assemblies will be the standard 12" x 2" size with a 5 bolt brake flange. To replace yours I recommend the etrailer Electric Trailer Brakes # AKEBRK-7-SA. This will come with a pair of self-adjusting brake assemblies (left hand and right hand). I like these etrailer brand brakes because they are durable, they perform well, and they are priced lower than other name brand options....

  • Can MORryde X-Factor Crossmembers Be Used With Roadmaster Comfort Ride System?
  • Hello Robert, thanks for reaching out. The Roadmaster Comfort Ride is a great choice for a suspension upgrade. This system is compatible with the MORryde X-Factor Crossmembers, so you can add those to all 3 hangers if you wish. One thing I would do is look at your hangers and make sure they are standard hangers welded to the frame. Make sure there are no obstructions like wiring or plumbing that would get in the way. You can do the MORryde X-Factor Crossmember # MR33WR, or you can do...

  • Recommended Replacement Center Cap for a 2021 Grand Design Reflection
  • John, I do believe we have something for you, but without any dimensions of the center cap it's going to be a bit difficult to say for sure, but from the looks of it the Trailer Wheel Center Cap Plug # AM90082 looks like it'll work. This center cap fit 1-7/8" holes and center caps with a 2.95" - 5.15" outer diameter. If you can let me know specifically what size center cap you're looking for I'd be happy to help.

  • What Information Do I Need to Find the Right Gen-Y Gooseneck for My 2022 GD Reflection 367BHS?
  • Hello Nathan, Great question. There are 2 key factors with finding the right Gen-Y Gooseneck, the pin box number, and the pin weight (tongue weight). I was able to look up the GVWR of your 2022 GD Reflection 367BHS which is 14,995 lbs. They have a special formula for getting you into the right Gooseneck, if you take the GVWR and times it by 0.22 you get 3,298.9, if you look at the chart that I attached that puts you into the 4,500 pound executive pin weight capacity. So now that we have...

  • Upgraded Suspension Parts for 2020 Grand Design Reflection 320MKS
  • Hey Joe, welcome back! With a 35" wheelbase the MORryde AllTrek 4000 Equalizers for Tandem Axle Trailers # MR29DR is the correct fit. I verified your Reflection has 6k axles on the Grand Design parts site so the # APUBR-8 is also correct and so is the capacity on the # e88SR. Did you account for the leaf springs flattening out over time? Assuming you did, these will work as a replacement with the 26" eye to eye measurement. The shackle strap length isn't listed on the parts site so you...

  • Replacing Leaf Springs And U-Bolts On A 2021 Grand Design 31MB
  • The 5-Leaf Double-Eye Spring # e34SR will be a good replacement for your 2021 Grand Design 31MB, provided the stock leaf spring is also 25-1/4" long. The suspension is all designed based on a specific length of spring, so it is critical that the replacement springs are identical in size to the stock springs. A 5-leaf 6,000 rated spring will definitely give you more support than the 4-leaf 5,200 lb springs. It is possible that you will need longer U-bolts, but it really depends on how...

  • Replacement Fridge Door Shelf for a Furrion Arctic 10 Cu Ft RV Refrigerator
  • Hey Bruce, thanks for reaching out! It sounds like you're looking for the Replacement Small Door Bin for Furrion Arctic 10 cu ft 12-Volt Built-In RV Refrigerators # FR57VD. If you have a different Furrion fridge then I recommend checking with your local appliance store to see if they have something that might work as Furrion doesn't have any other fridge door shelf replacements available.

  • Replacement AC Unit for a 2017 Grand Design Reflection 303 RLS
  • Hey Johnnie. The Advent Air RV Air Conditioner item # ADV26SR will indeed work in your 2017 Grand Design Reflection 303 RLS but you'll also need the compatible air distribution box. This AC unit has the new R32 refrigerant which are not compatible with the old R410A units. Plus their parts are being phased out.

  • Replacement for Dometic Brisk Air 2 in 2017 Grand Design Reflection 337RLS
  • Hey Paul! For a replacement AC on your 2017 Grand Design Reflection 337RLS I recommend the Furrion Chill Cube. The Chill Cube is the latest AC from Furrion and it is really impressive. This takes advantage of the new R32 refrigerant and uses a variable speed compressor for unmatched cooling power and efficiency. It is also unbelievably quiet. It looks like you have a ducted system so you can choose from the following: -Furrion Chill Cube RV Air Conditioner w Air Distribution Box - Ducted...

  • Replacement For A Furrion FWHO9A-AM Tankless RV Water Heater
  • Furrion/Lippert love to change the part numbers constantly on their products so it can be a bit tricky to find exactly what you're looking for if you don't know the right places to look. The FWHO9A-AM refers to the unit without the door, which would be part # FR93FR for our website. If you need the door as well then we have the following sizes: 16" x 16" Door # FR98SR 16" x 18" Door # FR48SR 18" x 18" Door # FR68SR If you plan on completing the installation yourself you'll also need...

  • Best Bike Rack For Carrying Tow E-Bikes On A Grand Design 260RD 5th Wheel
  • Hey Patti, thanks for reaching out. The Swagman E-Spec Pro Bike Rack # S45SR is a solid option for this. It can hold two bikes weighing up to 70 lbs apiece on a 5th wheel, and it does not have a minimum tongue weight capacity limitation like the Hollywood rack you mentioned. As long as the weight of the bikes plus the rack is under 300 lbs you'll be good to go there. If you need something with an 80 lb per bike rating, we do have the Hollywood Racks Sport Rider SE # HLY84FR. This is rated...

  • Can Progressive Dynamics 9300 Converter be Used on a 2017 Grand Design?
  • Hey Mitch, thanks for reaching out! The Progressive Dynamics 9300 Series RV Converter Charger # PD79RR can be used to charge 2 lithium batteries. I'm not sure what came on your 2017 Grand Design, but this measures 8" long x 9" wide x 3-5/8" deep, so you can compare this to the space that you have. Does this seem like it will work for you?

  • How To Carry Two Bikes And A Generator While Towing A Fifth Wheel Trailer
  • I have another option, but unfortunately none of the cargo carrier bike rack combos are rated for use on a 5th wheel trailer like your 2021 Grand Design Reflection. Instead I recommend using a front mount trailer hitch receiver on your truck with the 17x46 Curt Cargo Carrier for 1-1/4" and 2" Hitches # C18145 to carry your 100lb generator. This cargo carrier weighs in at 28lbs, and has a 500lb weight capacity making it plenty strong to carry your generator. You will want to make sure you...

  • Bearing Kit for 6k Axle of Grand Design 337RLS Fifth Wheel Trailer
  • Hey Steven, since we know you have a 6k rated axle the correct bearing kit that includes a grease seal would be the part # BK3-100. Did you have bearing issues or are you looking for a backup set to keep around just in case?

  • How to Adjust the Pivot Arms on a B&W Companion
  • Hey Thomas, congrats on your new trailer. You might have to play around with the different positioning of the pivot arms once you get the trailer home. There's no of knowing exactly what position you'll need without knowing the pin box location, the width of trailer, and the shape of the trailer nose in relation to how tall your truck is. I attached a screenshot from the instructions below. I recommend setting the pivot arms at the highest with the most clearance, top right. This will...

  • What Is The Max PSI Rating For The Aluminum Eagle Trailer Wheel LH48VR?
  • Hello Phillip, thanks for reaching out. Trailer rims like the Aluminum Eagle Trailer Wheel # LH48VR do not have a PSI rating. They can handle the PSI of any 16" trailer tire. The actual PSI rating is determined by the valve stem, which for the # LH48VR wheel is a rubber valve stem rated for up to 80 PSI. If your tires go higher than 80 PSI, replace the rubber valve stems with the metal valve stem part # AM20906 which are rated for over 200 PSI.

  • What Is The Max PSI Rating for a Lionshead Jaguar Wheel?
  • Hey John, welcome back and thanks for all the information! The Lionshead wheels like the Aluminum Liger item # LH98VR you were looking at, don't have a max PSI rating but the valve stems that typically come with them item # AM20904 top out at 80 psi. I recommend checking your valve stems and if necessary replacing them with the Americana Metal, Bolt-In Valve Stem item # AM20906. These are rated for over 200 PSI so they will work with your 110 PSI tires. If you have any additional questions,...

  • Replacement Control Module for Lippert Ground Control 304135
  • Hey Craig! Is this a Lippert Ground Control system? Is the part actually 304136? I asked Lippert and they said they don't have anything under 304135. If it is the 304136 the correct replacement is the Replacement Control Module for Lippert Ground Control 3.0 Electric Leveling System # LC304136.
