I know that Lippert made the axles and springs. But Lippert also makes the axles and springs that are on the near identical RKS and Forest River spec'd that trailer to have 5000# axles and springs...so I feel that I can in fact blame Forest River. The carrying capacity on that trailer is 2900#. The brochure lists the empty weight for the RKS at 30# more that what the tag on my trailer says it weighs empty. I think part of the problem stems from the fact that when I ordered my trailer it was suppose to weigh 5985#. When it was delivered it weighed 6234#. Maybe Forest River didn't allow for the increase in empty weight.

Keep in mind the trailer as a whole is engineered to a spec.
Just because the other unit has 5k springs in it doesn't mean yours should.
I bet the frame is also heavier / bigger .

I have no way to check the frame but was told by FR the last time this happened that the RKS is built on the same frame. I only was trying to find someone who had one to see try to understand why the ccc was so much greater than my trailer.

If you lived in any of the North Eastern States, I could understand why they didn't last. The further north you go, the worse the roads!

I live in Ohio but have camped in most of US states. And yes the roads your way as well as northern Michigan are hard on any thing that travels on them.

Gvwr is 7700# it looks to me like about
1400# of ccc
Those are just about my numbers on our Weekend Warrior. Axles are holding up barely but been through an unusual number wheel bearings and those C tires blew twice, with thank God reasonably light damage. The Carlisle E's are really holding up but 3500 lb axles on a 25 foot body is just too light

Do to any number of reasons just about everything is engineered to close specs with little to no wiggle room..... The axles look to be correct but I wonder if there is any accounting for the poor road conditions just about everywhere??



Our fifth wheel has two six thousand pound axles the pin weight is about 2500 lbs and the stated max trailer capacity is 14500......... that would be at the limit hopefully there is a safety factor built in but I would not want to push the max. capacity.......

Im not saying you dont have a problem but by the numbers it seems within spec. If you are running near max and running that all the time then fatigue and strain will run its course causing failure. Just like everything else if you run it at max.

That brochure weight is always low under the disclaimer it doesn't include options and a few other exclusions. Makes a trailer look lighter/easier to tow than it really is & makes the ccc look higher. But that issue isn't unique to your model. What does your factory sticker say the GVWR of the trailer is? And if you have a scale weight loaded for camping what was that?

There are some threads on here with this type of issue for heavy 5ers where the frames/axles/suspension have issues, but seems less common on travel trailers. What exactly was the failure on the 2 previous sets of axles & springs?
