I just had the moryde shackles and 4 wheel disc brakes added to my 38RL and what a difference! I held off on the independent suspension to see if the shackles and extra travel from the moryde was sufficient. I know you are talking about the Lippert but look at the moryde also. The ride is totally different now and the stoping power and distance is totally safe feeling now.

That's my future upgrade, the MorRyde SRE4000, just can't justify $3k for the IS. I've did the heavy shackles/wet bolts with bronze bushings in everything, now new disc brakes & H rated tires so should be in good shape til the equalizers wear out.

I could not justify that cost either so I went with the SRE4000 originally... coming from a 5er that had the IS there was a difference in the ride.. so I bucked up and sold the slightly used SRE4000 and upgraded to the IS , there is a big difference... drove 800 miles out to Indiana with the SRE4000, and home with the IS... wont have another trailer without the IS

I did 8k IS and Kodiak disc brakes over three years and 26,000 miles ago. will never go back and will never own another 5th wheel without either. There is that much of a difference. And then you add in the peace of mind with no axles, no springs, no bushings .........

Total for both when I did it was $6400.00 I believe the IS alone now is about $3400 but Joe would know better.

I agree, since I fulltime and move about every two week year round, I went ahead with the MoRyde 8K IS, Disc Brakes and MoRyde Pin Box last summer.
What a difference, great ride, fantastic braking response.

I paid $3740.00 in June for the 8K IS.... they took off my sre4000 and boxed it up so I could ship it to someone ( on here ).. they added ( supplied by me ) Timken Bearings... and that cost included OT for Saturday work, since I could not get out there early enough to have it done on regular time.it would have been $3200.00 on regular time

While the IS is more expensive, if you do much traveling it's well worth the extra cost by eliminating all the weak links in the OEM Suspension.
We're on our third unit with Mor/ryde IS and Disc Brakes, with approx 80K miles total without any suspension issues.

Did it comes with wheels and tires or was that also separate?

Gregg ,

Wheels and tires are separate... either call Ron for those , or call Scott at Trailer Tire and Wheels... Back in 3/2015 I paid $2650.00 for 4 of the Goodyear G-114 17.5's on the Hi-spec series 03 polished wheels.. That included all lug nuts and center caps , balanced and shipping ...
But I believe Ron's deal is a better one..

If you want to "BULLET PROOF" your under carriage , the BEST option is to go all in like some of us... And ONLY YOU can decide if you can/want to do all that..

Perhaps you can upgrade in steps ?
In NO particular order::

-- disc brakes
-- IS
-- 17.5 wheels

Thanks Joe,

For safety, I agree with your assessment. I've already been in touch with Titan Guy. His prices and service are 1st rate. The wrinkle came with the Morryde IS System. I've heard several of you discussing this set up. If I went this way, I would have to install the IS system, tires and wheels at the same time as I am upgrading to 8000#.

For the money, I just need to be absolutely sure that it really is worth it. I am content with the research between the Dexter axles and IS System. There are differences. But given that the average RV Owner will not keep the existing unit for the long term (due to trade ins for newer models or getting out all together), is there a significant enough difference to warrant the additional expense. When it comes to trade in, I would expect that there will be a loss for ANYTHING we add to these units. The real challenge is "when" to trade and how much physical travel we experience. Tires and Disc Brakes are a no-brainer. But as for the ride quality of the RV, will we really really prevent damage beyond the Dexter 8000# axles? We're talking about a $2000 difference. I do see your point for the "ultimate" in road protection. There is a engineering difference.

For those full-timing, will you be keeping your unit forever? Have you or are you considering something different (i.e. Motorhome, newer year model or getting out all together)?

We installed the Centrepoint and Disk Brakes for less than the cost of just the IS system. We have noted a substantial difference in the ride quality in the 5,000 mls completed so far.

Is the ride quality and safety of IS any better, I suspect it most likely has a better ride and it eliminates the springs. However, are those improvements worth the significant additional cost? For us the answer was no and we are very happy with the improvement provided by Centrepoint, as a very reasonable cost.

It's a decision each owner has to make on their own.
The IS eliminates the OEM axle tubes, gives you 5 inches of travel on each wheel, independent of the others, a shock at each wheel, and the ability to align each wheel independently. No more bending axle tubes. Plus you have no shackles, wet bolts, nylon or brass bushings.
When you actually look under a unit with the IS, you'll understand the differences.
No you will never recoup the cost of upgrades, just the way it is, but for us it's been worth the cost on all 3 fifthwheels we've owned, but then we put on a lot of miles.

I got disk brakes from the factory, upgraded to the 8k MorRyde IS system after about a year, then about a year later went with "H" tires and wheels.

Very happy I did. Ride improvement over factory "G" tires and standard suspension is remarkable.

I love the idea and it makes complete sense to be able to inflate/deflate each CenterPoint airbag. I'm just wondering why my 2017 RW3401RL with 8000# axles / centerPoint suspension, connected both airbag's airlines via a tee at the front axle to a single inflation/deflation point mounted next to the batteries? :-/

Wow, the factory sure got that one wrong. Our Centrepoint was installed by Lippert and we have 2 inflation/deflation points, each with an air gauge just aft of the fwd stairs.

We can inflate each side depending on the relative weight. Lippert techs recommended 60 psi on driver side ans 40 psi passenger side.
