Expert Answers about Grand Design


  • Suspension Enhancement Recommendation for 2017 Grand Design Reflection 5TH Wheel With Uneven Load
  • The best thing you can do for your suspension on your 2017 Grand Design Reflection 337RLS is to add some jounce springs. The Overslung SumoSprings # SS26MV provide additional stability to your leaf springs. They will also help to reduce the amount your suspension compresses on the kitchen slide side due to the additional weight on that side of the trailer. You will need 2 of these kits for your tandem axles. If you were to install 7,000LB Springs # e64SR your suspension will be stiffer...

Yes this will fully charge your batteries even though they are 10 foot away roughly.

  • Replacement Leaf Spring for 7k Rated Trailer Axle
  • We have one 7k axle rated leaf spring with the part # e64SR which is 24-7/8 inches. You'd need to measure the current springs on your trailer to make sure this would be correct size. Hopefully it is as this is only spring size we have in this capacity.

  • Parts Needed to Convert to Electric Over Hydraulic Disc Brakes on 2018 Grand Design 5th Wheel
  • To get your electric drum brakes converted over to an electric over hydraulic dis brake set up, the HydraStar Electric Over Hydraulic Actuator Kit for Disc Brakes - 1,600 psi # HBA16-252-82 is a great place to start. This includes all the lines/fittings needed for a single or double axle trailer as well as the actuator and the break away kit as well. To complete the system, you will need the Kodiak Disc Brake Kit - 12" Hub/Rotor - 6 on 5-1/2 - Dacromet - 5,200 lbs to 6,000 lbs # K2HR526D....

  • Recommended Way to Add Disc Brakes to 2020 Momentum 376THS
  • The first thing you'd want is the Kodiak Disc Brake Kit # K2HR79E for each axle. This is a 7k kit with an oil bath dust cover that fits your current spindles and also is compatible with your wheel size. For bearings you'd need to order the # 25580 and # 02475 separately as well as the seal # 10-63 as they are not included. Since you have a triple axle trailer you'd need three of the disc brake kits and 6 each of the bearings and seals. For an actuator kit the best option is the Hydrastar...

  • Best Camera System to See Behind Travel Trailer
  • The best camera system for the rear of your travel trailer would be the Furrion Vision S part # FOS43TASF that you referenced. This camera is mounted in a bracket that will allow you to adjust up and down the viewing angle so you can easily see 30 foot or more behind you and the angle is wide enough that you'd be able to see to the sides well too. The Vision S has the best reputation for reliability and reception too so it's going to work really well for you.

  • Adding Higher Weight Capacity Spring Bars To My Current Weight Distribution Hitch
  • If you figure your dry weight on your 30 ft Grand Design has a 581 lb tongue weight. It is close to the lowest weight rating of the current bar you have. You only have a 219 lb gap before you are at the max for that bar. If your family is anything like mine bringing 200 lbs of stuff on a camping trip in nothing. I suggest getting the 800-1200 lb bars to be safe. If you are questioning it now you will always think about it if you don't. And most storage basements on travel trailers are...

  • What Axle Rating Should Leaf Spring be for a 4,400 lb Trailer Axle
  • You'd want to go with leaf springs that are rated by axle that matches what your trailer axle is. So since you have a 4,400 lb axle a 4,500 lb axle leaf spring like the part # e72SR would work really great. This spring is 26 inches long.

  • Replacement Strut for Solera Flat Awning Support Arm that Won't Hold in Place
  • I would agree that it does sound like you need a new strut for your Solera Pitch Arm part # LC281154 that you referenced and for that you'd want the part # LC260282 and you'd be set.

  • Recommended Replacement Hose From Propane Tank to Regulator on 5th Wheel
  • The hose and fittings sizes are standardized for RV's. Therefore, what you have is going to be a type 1 to either a 1/4" NPT or 1/4" Male Inverter Flare. If you have the former I recommend part # 100473-12 or part # 37207-30715 if you have the latter. That said, I get why you're confused as these fittings don't actually mic out to 1/4", they will measure larger but that does not correlate to their nominal size which would be the same for measuring any sort of NPT fitting.

  • Picking Out Replacement Trailer Jack for Tennessee Boat Trailer
  • That really does look like a Fulton swivel jack base like what the part # FXP15W is designed to fit but without you confirming that it's a Fulton we can't guarantee it would work.

  • Cover Recommendation for 2023 Imagine 22LDE Grand Design
  • Since your 2023 Imagine 22LDE Grand Design is a little over 26 feet in length the Adco Olefin HD RV Cover part # AD87ZR is your best option. This is the correct size, provides the best protection in all climates, has zippered access panels in case you need to get into the trailer and has the easiest install since it has weighted straps you can throw under the trailer instead of having to crawl underneath it.

  • Recommended Equal-i-zer Weight Distribution System for 2019 Grand Design Imagine 2670MK
  • For your 2019 Grand Design Imagine 2670MK Trailer the higher-rated Equal-i-zer 14/1.4K Weight Distribution System # EQ37140ET will be the better option. Since your Grand Design can weigh up to 8,500 pounds when fully loaded, you are looking at a loaded tongue weight of around 850 to 1,275 pounds. We can calculate this because a trailer's tongue weight should be 10 to 15 percent of its total weight. When picking out a weight distribution system the most important factor to consider is...

  • Will Furrion Vison S RV Observation Camera System Work On 2021 Grand Design Transcend Xplor 297QB?
  • The Furrion Vision S Wireless RV Observation Camera System w/ Side Marker Light Cameras - 5" Screen # FCE48TASL-05 you were looking at will work with your 2021 Grand Design Transcend Xplor 297QB since it is prewired for the Furrion cameras and is a great choice as it not only gives you a backup camera, but also two side view cameras. The monitor of the # FCE48TASL-05 can be used with up to 4 cameras, so you could add the Furrion Vision S Wireless RV Backup Camera # FCN48TASF over the entry...

  • Troubleshooting WatchDog E2 Error Code
  • The E2 error of your Watchdog part # HU27FR means you have a voltage issue on line 2. The Watchdog has determined that the voltage coming in has either exceeded 132 volts or is below 104 volts. If you press the Live Reading button you can see what the voltage is at this time. Most likely it's low due to the AC drawing a lot. A Softstart will help and since you have a 2 AC setup you'd need the part # SSR44FR.

  • Can a Hopkins Camera System be Used with a Furrion Factory Camera Prewire Setup
  • I'm sorry but the Furrion systems and the Hopkins systems are not compatible with each other. The most cost effective solution I have is the Furrion Vision S Wireless RV Backup Camera System w/ Night Vision part # FOS43TASF if you want to use that particular base. You do have the option of not using the Furrion base and the power from the marker lights instead and still be able to use the Hopkins VueSMART RV and Trailer Backup Camera part # HM34FR and view it through your smart phone.

  • How to Level Trailer that Sits Nose High After Adjusting Hitch Height for Bed Rail Clearance
  • Ideally your 5th wheel trailer sits as level as possible and also there's at least 6 inches of clearance between the overhang of the trailer and the bed rails of the truck. In a situation like yours where having the needed bed rail clearance causes the trailer to sit nose high you would have to lift the trailer suspension, or if the truck happens to have a lift kit you'd need to remove it and go back to stock ride height. For a tandem axle trailer like yours we do have a 2-1/4 inch lift...

  • Is Installation of One MORryde X-Factor Crossmember Enough on 2019 Grand Design Reflection 230RL
  • Adding one MORryde X-Factor Crossmember # MR33WR to your 2019 Grand Design Reflection 230RL will definitely help. However, for full support and stability on a tandem axle 5th wheel like yours you want to install 3. These attach to the leaf spring hangers, running directly across between them. As long as your drain is not between the hangers it won't be a problem.
