Video Transcript for Manufacturer Discussion - Roadmaster Comfort Ride System

Hello neighbors, it's Brad here from etrailer, and today I have Jeff from Roadmaster. And we're gonna be taking a look at something that a lot of people don't think about on their campers, and that's, well suspension, you know And a lot of times people buy a camper, and they go, "Well, it is what it is. That's the ride that we're gonna get." And that's not necessarily the case, correct Absolutely. You can always turn around and increase the customer's ride on their fifth wheel, or their travel trailer, by just doing a simple modification and changing it out to slipper springs. There are other several products that you can look at as well. So a slipper spring, for those of you that don't know, what exactly is that compared to a normal just leaf spring So a normal leaf spring, what you have is an equalizer that's in between that's connected with links.

So typically what happens is, is as the energy is being absorbed by one wheel, it's actually being transferred into the other axle, and so on and so forth. So you get a lot of unnecessary movement back and forth, up and down, out, and outward as well. But what we'll primarily do, is try to reduce all the shock that's going into the trailer. So is that lease spring as a slipper, it becomes almost floating in the sense, correct Correct. So basically what it does, our picture that we have here is my unit after I did the install.

So typically what we do is remove the equalizer. We mount our slipper spring box. And then what happens is, is we have our slipper spring that goes into the box. And as that, as your wheel hits a bump, the spring actually slides in and out of the slipper spring box. So does that, with the slipper spring, does that keep the axles a little bit more in-line than a traditional leaf spring Yes, it does.

So whenever you hit a bump, what you're gonna notice is, we have some slow motion video as well, but you, when we hit a bump, you'll actually notice that the wheel, the axle's moving vertically instead of horizontally also. Brad As the a way suspension should be. Jeff Correct. Correct. So without a slip or spring or just normal suspension, you have a story with your own trailer.

Not that many miles on it, and maybe some issues with bushings. Yeah. So basically what happened here, is you're looking at my newer fifth wheel that I have. I recently talked to one of my dealers that was up in Northern California. He said, "Hey, did etrailer put your system on yet" I said, "No, not yet. It's actually in my garage. I haven't put it on yet." He's like, "Well, what are you waiting for" I was like, "Well, just been really busy. Haven't had the opportunity to do it yet." He's like, "Well, are you getting ready to do any service" I was like, "Yeah, I'm gonna go pack my bearings." He says, "Well, when you do so," he says, "Do me a favor." He says, "Pull one of the bolts out." He goes, "For your existing spring." He goes, "Just kinda let me know what you see." So I went home, packed my bearings, did exactly what he said, pulled that, pulled that bolt out, looked at it, and the, the bronze bushing inside was completely wore out. And so once I determined that, I decided to go ahead and do the install of my, on my own for the comfort ride system. So, as far as, okay, this is your own driveway, you did this yourself. Yeah, it's actually at a campground in Needles, California. Okay. How bad was it to do So typically, I mean we normally for a double axle, eight hours, for a triple axle, 10. In this case, because I'm very familiar with the product, I do it quite often. I was actually able to do it in under eight hours. Okay. And as far as the kit, obviously we have a triple axle here. So you have the two boxes. Does it also come with the shocks So the shock absorbers are separate, but a complete kit will be the slipper spring, the shot, the slipper spring box, and then you add the shock get, the shock kit to it. And basically what happens is, is we're looking at upwards of 80% increase in rideability for that, for that trailer. Okay. And then as far as choosing a comfort ride, you know, say someone's kinda landed, that they want to get the comfort ride, how do they determine which kit is right for them So if they wanted to, to look at which kit's gonna be proper for them, so we have the shock kit, which is separate from the slipper spring kit. What we need to know is diameter of the axle. Okay So once we determine the diameter of the axle, that gives you the proper shock kit. And then what we need to know is the weight capacity of the spring. And once we have those two, we can set you up with the proper kit. Okay. Now living with it, you know, a lot of times with suspension people go, "Okay, it's, it's, you know, a decent amount of money be putting in this. A little bit of work to get it installed. Does it really make a difference" It makes a night and day difference. Especially when you're towing, you'll notice that you don't get the excessive wag out of your, out of your trailer when you're driving down the road. Especially if you're hitting bumps or potholes, you're gonna notice that there's a lot less energy being transferred into your coach. So a lot of times people notice, "Hey, I got screws that are starting to back out, or I'm starting to having to seal my coach more often. Because we're absorbing all that extra energy down here with the shock absorbers, we're noticing that that's not quite happening quite as frequently. Now, there's definitely a lot of different options when it comes to, you know, suspension enhancement. But why would someone want Roadmaster versus anything else that's out there Well, we are a US manufacturer. We manufacture everything ourselves in Vancouver, Washington. If you ever get the opportunity to come on out, we'd love to give you a tour. But more importantly, I'd say we do manufacture all this in-house, so it is a made in the USA product. We're very proud to advertise that, but we also back it with a lifetime warranty, 'cause we are able to build that quality into the product. And that's peace of mind. I mean, you one and done. Exactly. You buy it, you get to enjoy it. You know it, the warranty's gonna outlast the trailer more than likely. Jeff Exactly. So that's pretty cool. So adding this comfort ride to a travel trailer is definitely gonna enhance your driving experience, as it, more suspension is generally a good thing. You know, as you're towing down, your truck's gonna be squattin', and you have points that are gonna pivot. But each of those points are potentials for it to get, to be a little bit harsher ride. And factory suspension on travel trailers are, well they're pretty old school to say the least. Pretty old school. Yeah. And this is a much better system. Yeah, absolutely. I mean, having slipper springs, as well as the shocks, it's really gonna give you, well a comfortable ride. Yeah. And we're giving the customer independent suspension axle to axle. Which is awesome. Yeah. And that's really using, you know, newer technology, and putting it into stuff that should have caught up by now. But it's great that this is an option. So you know, if you're really hauling quite a bit, and you're not happy with the way that it goes down the road, this is gonna be a great option for not only your trailer, but all the contents inside of it. Jeff Exactly. And as far as the installation goes, if this is something that's maybe beyond your scope, you don't have the place to do it, the tools to do it, or even the want to do it, you can use our dealer locator, and that way you can find someone close to your area to get this installed for you. Huge thanks to Jeff for taking a second to give us a little bit of insight into the Comfort Ride for Roadmaster here. Yeah, definitely. Thank you. Thank you.

Roadmaster Comfort Ride Slipper Spring System - 7,000 lb Axle - RM-2570

Average Customer Rating:  4.7 out of 5 stars   (224 Customer Reviews)


by:

Needed a bit longer bolt than was provided on a trailer. These bolts added the extra length I needed and were a perfect fit. Didn’t have to bend them open or closed to get them through the tieplate holes.

Installed a year ago, I made a drilling template to help locate the frame mounting bracket screw holes. Installed a set on (2) fivers, spent average of 2.5 hours for total installation per fiver. Helped the ride of the trailer. Would certainly recommend the shock kit.



by:

Install wasn’t bad. Grand design welds a V bracket inside the spring hangers for more strength so that was my only challenge on install. This caused a problem on the center hanger as the spacer wouldn’t fit. Had to grind about a quarter inch off the spacer so it would fit as I could only bend the bottom of the hangers so much. Will be towing about 100 miles this weekend so it will be nice to hopefully not have broken drawers in the back of the trailer as well as shelves in the fridge door dislodged. I also did the X factor cross braces on the front and rear hangers for more strength. Will post back after we get more miles on it, but given all the other positive reviews I don’t think I’ll be unhappy.



by:

What a great product. The difference it made in our ride was outstanding. You almost forget you are towing a 35 ft 5th wheel behind you. We travel from West coast to East coast over all type roads and this product made such a difference. Sorry we didn't have it installed sooner. Definitely made a differance and would highly recommend to all Rv owners.



by:

I had a tech install the shocks on our 2019 Shasta Phoenix 37FE fifth wheel. He did an excellent job and now we experience a better ride and a lot less surprises when we arrive and open our camper door. Railroad crossing, terrible Georgia interstates, and ruff roads are allot smoother now with less bouncing.



by:

Not being able to experience riding in the 5th wheel RV it's difficult to state the ride quality. However, without a gas shock absorber system the spring suspension is allowed, "out of control movement". Frequently I inspect the suspension and I suspect the Roadmaster System is doing what it's designed for. I would recommend this product.

RE: MORryde RV Shackle Kit-2.25" Shackles-The Wet Shackle Kit is an improvement over stock. However, despite frequent maintenance, greasing, the bronze bushings need to be replaced. With that said, it would be prudent to mfg. the bushings using yellow brass for longevity. It would be appreciated if MORryde would provide all new replacement bushings. During maintenance a top quality tenacious waterproof grease is used.

Overall, doing business with e-trailer is outstanding.

1. The impression from "people"
was usually "why shocks on a camper", which I would answer "why shocks on your car".
2. The ride was much better; as you may imagine driving your car without shocks. And the sway was minimized & the braking effectiveness increase.
3. We've sold that RV and on our new one already planning the install; and including the wet bolts and mod on the leaf-spring hangers.



by:

My axles are attached above the leaf springs. This complicated the installation a bit but was not prohibitive. I have tandem axles and purchased two(2) of these kits for the trailer. Immediately, we noticed that the trailer was more stable when parked without the outriggers deployed. I wish I could get detailed drawing of the shock brackets. Knowing the designed angle where the shock absorbers mount would have been very helpful with the installation.

I am leaving for my first road trip and look forward to the increased stability during towing and not having the trailer contents thrown about during transport.



by:

Very good product. Instructions and video very good as I installed the suspension and shocks myself. Took me about a day.
I have put about 10,000 miles since the install. No problems & nothing coming loose. Helps to take some of the roughness out of the road vs standard equalizers



by:

OMG! After having the trailer bottom out on the stock springs while traversing a RR crossing, this system has proven to be amazing. Returning from a VA campground I crossed multiple RR crossings and traveled some rough pavement. I found I had left a bottle of shower soap on the ledge in the shower! It was still there when I set up in my yard. Not possible with the stock suspension!



by:

All travel trailers should be equipped with shock absorbers. Roadmaster nailed it with the brackets which fit perfectly. Be sure to order the longer u bolts.



by:

Along with the new springs....everything works as advertised. Well satisfied. No complaints.
I had to modify the one set of shock brackets to fit, as I have raised the trailer 5 inches
to match up with the 4 inch raised truck.
Otherwise...no swaying....no bouncing........no problems.
Thanks etrailer for your help.



by:

This is a great kit! Everything needed is included. Be sure to purchase the heavy duty wet bolt kit for the shackles.



by:

This has been the best upgrade on my toy hauler to date. Great smooth ride .



by:

We installed these on our 2022 Riverstone Legacy 39RKFB and without a doubt they have saved us on broken rims (many have this issue) and the ride was an instant upgrade. We drove a 6500-mile trip over the summer to ZION and Rockies and no issues at all. I installed them myself and recommend them as an inexpensive solution to expensive independent suspension.



by:

Installed two of theses on a Tracer 23RBS, 28Ft. Had everything needed for complete install, decent quality. Instructions had just enough info for proper install. Gas shocks a plus, anticipating a more stable ride.



by:

With all the proper tools, the install was only like 4 hours. I did this outside on a gravel driveway and then took to my local fire department where it was level to install the shocks. The ride difference was noticed immediately.



by:

After much research and evaluation I found the Road Master to be my first choice for our 2023 Grand Design Reflection Tandom Axle RV. The engineering, manufacturing and quality is demonstrated in this product. The components are heavy duty with clear instructions. I’ve not had the opportunity to install yet however before we embark on a 2 month tour, I’m confident in this added suspension package to assure a safe, comfortable ride.



by:

The suspension system is amazing! It feels like the 5th wheel is riding on coil springs. The shock absorbers make such a noticeable difference; why these aren't installed at the factory will forever puzzle me.
Installation was straight forward. The length and quality of current U-bolts allowed for reuse.
I was skeptical about the fasteners, until the first one was torqued to specs...it was soon apparent that the provided hardware was more than adequate for the job.
I wouldn't hesitate to purchase this system again, and I promote it as often as possible.
Thank you, and all the etrailer staff!



by:

So far so good on my 2015 Open Range 3X427BHS!

Overall, the old suspension system was just rusted and worn out and the tires were a maximum of 1" apart, which made me really nervous while pulling. It was tough to remove, but nothing a little WD-40 and some praying couldn't fix!

Installation was pretty straight forward using the included directions and [online video] University. Looking forward to seeing how it rides this weekend on our next trip.



by:

This is a great product, it smothered out my fifth wheel nearly eliminating the chucking.
