According to my research, your 2018 Grand Design Momentum 376TH should use a Lippert 1621HD bolt pattern. Therefore, any of the pin boxes that are designed to replace a Lippert 1621HD should be correct for you. I have attached a list of these for you. If you are looking for a Trailair Air Ride 5th Wheel Pin Box then part # LC158778 should be correct for you.
With that being said, trailer manufacturers do not provide us with information on the pin boxes they use so you will need to look... view full answer...
For a replacement circuit board you can use the Replacement Printed Circuit Board for MaxxAir MaxxFan Plus Roof Vents # MA10A04751KS. We have confirmed with MaxxAir that this is the correct for what you have. view full answer...
Hello Greg. We do offer one black water tank T-handle that is designed to work with an internally threaded shaft. It has a screw that inserts down thru the top of the handle. Take a look at the following:
Replacement Handle for LaSalle Bristol Cable-Actuated RV Waste Valves - Black Water Tank # 34490CMA1
This is designed to work specifically with the LaSalle Bristol Cable-Actuated RV Waste Valves such as part # 34466N4AB120GM. Generally, the handles are brand specific to the valve, and... view full answer...
I reached out to Roadmaster about the Comfort Ride Leaf Spring Suspension Kit w/ Shocks # RM-2460-2580 you are looking to install. While they are unable to give exact numbers for the length of travel on the leaf springs the shocks do have 5-1/2" of maximum travel. You may notice an initial change in ride height due to the new and heavier leaf springs but the system is not designed to increase your overall ride height on your 2018 Grand Design Momentum 351M 5th wheel camper. view full answer...
Since your 2014 Grand Design Momentum 385TH has 8k axles the correct SumoSprings kit would be the part # SS26MV for if your axles are under your leaf springs or part # SS33HR if they are above instead. view full answer...
I spoke with my contact from Roadmaster and she said that the steel used for the Roadmaster Comfort Ride Leaf Spring Suspension Kit w/ Shock Absorbers # RM-2460-2570 is from America.
Although American steel tends to be stronger, when it comes to leaf springs the biggest mistake people make is overloading them which does cause them to wear prematurely to the point of failure. No matter what kind of leaf springs you install on your trailer be sure that you stay within the weight ratings... view full answer...
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. view full answer...
If you are wanting to upgrade to disc brakes on your 2021 Grand Design Momentum 5th Wheel Toy Hauler, you are definitely in luck. We actually have an install video of the Kodiak Disc Brake Kit # K2HR712E being installed on a 2020 Momentum and is the one I recommend going with. These have an E-coat finish that provides good corrosion resistance and can actually be used for freshwater and limited saltwater use, though I don't recommend submerging your toy hauler. This kit will also match... view full answer...
There is no difference between the MORryde Wall RV TV Mount # MR57RR and TV56-129H. TV56-129H is just MORryde's part number, while the other is our part number for our system. view full answer...
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. view full answer...
The majority of 7000lb axles like the Dexter 7000lb axles you have on your 2020 Grand Design Momentum 351M use inner bearing # 25580 and outer bearing # 14125A but I recommend double checking this as there are still some odd bearing combination options.
The easiest way to confirm your bearing combination is by removing one of your hubs and looking for the bearing numbers stamped on the face of each bearing as shown in the included picture of the # L44649.
If you do have the # 25580 and... view full answer...
The Roadmaster Comfort Ride shock kit part # RM-2460 is going to give you the smoothest ride quality and have the easier install so that would be what I would recommend for your 2017 Grand Design 328M toy hauler.
I attached an install video link to this page that shows it install on a similar 2017 Grand Design for you to check out as well. view full answer...
For a tester that allows you to test the 7-way of your truck all you'd need is the part # 6562 which plugs right in and will tell you which circuit is being activated. view full answer...
The Wet Equalizer Bolt with Locknut and Grease Zerk # 126B2 and Bronze Bushing # D014-077-00 can be used to replace the wet bolts that are frozen on your 2020 Grand Design Momentum 351M.
The wet bolts on the Momentum were most likely not serviced properly from the dealer/owner of the camper is my guess. If water got into the bushings and caused rust to develop this is what I feel may be causing you to not be able to install grease into the bolt. Typically the grease zerk will be the first... view full answer...
If you need an axle replacement because one is damaged, you will be fine sticking with the 7,000 lb axles you currently have. All you would need to do is get the hub face to hub face measurement to choose the right axle length. We have 94" # 8327864 and 95" # 8327834 7k Dexter axle replacements. Unfortunately, we do not have any 8,000 lb axles available.
I suspect the reason you want to add 8k axles is based on the GVWR of your 2018 Grand Design Momentum 351. The one thing you need to... view full answer...
If the suspension of your 2019 Grand Design 351M is currently in good working order but you want to improve what you have by making the ride quality smoother you could go with just the shock portion of the Roadmaster Comfort Ride with part # RM-2470. You'd want to measure the diameter of your axles though. If they are 3-1/2 inch like what most 8k axles fit then the correct kit is the # RM-2470. If they instead are 3 inch you'd want the part # RM-2460. view full answer...

The Adco Olefin HD All-Climate + Wind RV Cover for 5th Wheel Toy Hauler - Up to 43' Long - Gray # AD89ZR has a fabric thickness of approximately 0.035" thick for the top panel and approximately 0.015" thick for the side panels. The top is 1-ply Olefin material and the sides are 3-ply polypropylene. view full answer...
I would be happy to help!
When measuring for new leaf springs you need to either take them off of the trailer, or jack up the side of the trailer so that the axle is not carrying any weight.
Based on the pictures of the leaf springs on your 2017 Grand Design Momentum 398M with Triple 7000lb axles they do look a bit flat, but when weight is not on them they should get a curve back in them.
If you can tell me how long from center of spring eye to center of spring eye the springs are, I... view full answer...
