I may have to get a 68RFE in my new truck.

Stewart,

You mention the truck riding rough with the 5er connected, but what kind of road you driving on to get ROUGH? I've been towing 5ers since 2000, all heavy, and last two only had the MoRyde pin box, and I never felt any of them felt ROUGH, except occasional bad railroad tracks, or badly chuck holed roads. ALL of mine actually road/ride smother under load. My current 5500 solo with stiff tires and heavy springs pretty much rides like the roads it's on.

Just trying to get a COMMON understanding of ROUGH ride AND expectations for a truck rated 14KLbs GVWR and 40KLbs GCWR.

It seems your brief experience with this truck is not matching with that of the VETERAN owners of air assist max tow 3500s. And you could actually be at the point of reckoning where you have found what works for you, even if it doesn't match the majority, which is fine too.

Finally, it sounds like you're figuring out your setup.

Congrats and good luck.

Cheers, Ron

I am surprised when someone goes out and gets a 3K air ride pin box, without trying the MorRyde, which is usually the solution to a lot of chucking. All either one is doing is masking the problem. It does not just magically go away with air ride pin box or MorRyde . My fifth wheel with the MorRyde is as smooth as you would want. 38' and 15,500 GVWR

 

[Cummins2014]

Ok guys I did try the alternative ride height with the trailer and it rode wayyyyyyyy worse and kind of REALLY bouncy I put it back to normal height and it was great, now this may be because I use the Anderson hitch but man the truck goes up hills really nice.

That Andersen is not going to make anymore difference then any other FIXED hitch. I see if not mistaken you have the Andersen adapter turned around to the forward position ,putting the fifth wheel closer to the cab, so you have to be at least over the axles or forward of it ?? Could it be the combination of that air ride suspension, and air ride pin box, TOO much bounce there. ??

Did you even try towing with the MorRyde, or did you go straight to that air ride ??? MorRyde are surprisingly smooth. What is the GVWR of your fifth wheel . I am thinking its 15,500-16,500 .

 

[Cummins2014]

Something doesn’t sound right.

Since the truck is lower in ALT did you check that the trailair didn’t need adjustment?

Could the Anderson hitch be taking more weight off the front axle than you think, and ALT makes it worse? Maybe you should spend some time at the scales??

You really want to be in ALT with a trailer. This is what the suspension is designed for.

As far as I can see in his pictures he has the adapter in the forward position, putting the fifth wheel closer to the cab, its a fixed hitch, like any other hitch, just attaches differently to the pin box with the adapter. That hitch cannot make any more difference then the conventional.

Pretty sure the Andersen he has can only be mounted a certain way, unlike my rail mount Andersen, which can be mounted either way on the offset . His is also offset ,but goes in just one position, the adapter can be turned either way.

I have the Andersen, and I tow with it in the rear position on the adapter ,my truck is a short bed . Puts the kingpin slightly to the rear of the axle. I also tow with a Reese slider thats slightly forward of the axle, and there is ABSOLUTELY no difference what-so-ever. I cannot tell the difference in them towing.

I agree, it shouldn't make a difference what hitch.

I really like the MorRyde setup, and IMHO it's better than an air setup. The MorRyde dampens the road forces, where the trailair dampens the king pin forces. Road forces are felt more in the cab than pin weight.

It surprise me the OP, got rid of the MoRyde it appears he never towed with it, thats unfortunate if he didn't try it first. IMO they are pretty impressive.

I never use the more ride hit in the more ride pin box and that's okay the only thing I was complaining about was when I put it on the alternative fight it feels like a really lower the back end of the truck maybe it's real maybe it's imagine whatever it's ride so much better at the normal height just my opinion it's okay that's my opinion I don't have to be right and you don't have to be wrong but we can sing a different song we can agree to disagree.

Would you care to tell us what there was about the MoRyde pin box for you to get rid of it . Its always nice to know what is wrong with a certain products. I don't know or heard of anyone wanting to get rid of the MorRyde. MorRyde pin boxes are pretty popular, and do get the job done very nicely.

I couldn't ask for a better ride with aftermarket airbags, and the MorRyde pin box, no complaints here, plus mine is a short bed Megacab. No disagreeing here, just would be nice if you would explain things, plus the GVWR of your fifth wheel

It does lower the truck, that's the entire point in it... and why auto-level works so great with trailers. It allows use of the overload springs (which overload might be the wrong term as they aren't used/designed like overloads).

Those lower springs are important for heavy loads to remove pressure from the bags. This makes the ride smoother, and adds stability to it. By not using ALT you are supporting all of the pin weight on the airbags, which will create a harsher and less stable ride. The springs do need to compress some and absorb some of the weight to gain stability, this is true on any spring with supplemental airbags.

Give it some miles and see. I've had 3K of payload on my auto-level multiple times for several trips so far and ALT always gives a better more stable ride.

Have you adjusted the trailair for the lower ride height? You could be inducing harshness with that setup if it's not adjusted properly.

Yes it lowers the by around 2".

Yes it is stiffer in ALT because the Overload springs are in use the.

ALT= more load on the leaf springs.

NORM= more load on the air springs.

If it fits your driving habits in NORM then go for it.

Still don't care to tell us about the MoRyde pin box, if not just say it. Its good to know if a product is not getting the job done in certain conditions. FYI MorRyde is an excellent product.

I think I like my aftermarket air bags more ,and more all the time One fact is for sure I have complete control over the air pressure, and have changed it on the fly more then once for road conditions. You get whatever on this OE system good or bad.

Not saying its a bad system, can't do that , never had it . Just the one fact with the OP having a leaking air bag he was dead in the water as far as being able to tow, thats enough right there for me to not want it. Plus aftermarket is much cheaper.

So far I like my OE setup better than the aftermarket ones I had on the 05, but those also worked quite well.... once I learned how much sag to give the rear suspension. Too little sag, which is very common looking at peoples rigs running down the road, gave horrible performance.

I can't say I've ever had to adjust pressure mid trip, once it was set correctly.

A leaking bag on this setup will not leave you stranded, it would be similar to a leaking aftermarket bag. You can still drive and make it home, now the 2500 setup is quite different and would leave you stranded.

It just sounded like he couldn't tow with that one bag not holding air. I guess if he had too he could have ??

Not knowing the difference I like aftermarket , it works .

Why this?
Wouldn't it just sit on the blocks like heavy overloaded were the air goes into fault mode?
To my knowledge all these air spring setup protects themselves from overload, not just RAM, all of them that I know, Toyota, Rangerover, Audi, Mercedes.

I would have to look closer, but without any actual spring the difference in rear height might be too extreme to drive anywhere. At least on the 3500 there are main springs still. You could deflate the good side if needed, and get home on springs alone. The main leaves with the lower leaves are pretty strong.

When the 2500 goes into overload it's my understanding it still has air in it, probably max allowable pressure, just that it won't/can't get to the proper ride height.

 

[Stuart Carter Brandt]

I have a leveled out jayco 377rlbh right here check it out.

 

[Ozymandias]

Yeah, sur it would sit on the blocks, pretty low, but still driveable.

Think about the Hillbillies, putting the bed full with fresh concrete and such stuff.
That system must to be idiot-proof.

Ok I have a question tonight a little red light went on next to the what's available as far as mileage is concerned a little red light showed up with a trailer looks like a trailer and then with a round circle and then a in a line through it what is this mean guys I'm not sure maybe it means I unplug something or I don't know???????????
