New Curt Independent Suspension

[Schiefswret]

Wondering if anyone knows if GD is investigating/considering the new CURT Independent Trailer Suspension at any time in the future.
If anyone knows anything about this, please advise.

Dave,

I have not heard that GD will be installing this, and have not heard of this suspension yet, it looks pretty good. This is an item we can ask GD when we are there in April.

Good idea Brian. I saw the Curt video and was really impressed. I’m eager to find out if it is capable of and will be offered as a swap-out for TT’s with OEM tandem axels.
if so, barring some absurd price, I’d be one of the first ones in line!

I was at the Lippert upgrade installation facility (in Goshen, Elkhart County Indiana yesterday) having an automatic leveling system installed on my travel trailer. I asked whether they had an independent suspension, like Morryde. The answer was yes, sold under the Curt brand. The Lippert person told me that one manufacturer will be using it very soon on trailers sold at retail. I was further told that it takes an engineer time to do calculations for an upgrade on an existing trailer. In view of this complication of getting an engineer involved, and the high price (was not told what it was), it may have been inferred that I would be better off with the Morryde independent suspension than the Curt independent suspension.

Anything with proper damping and a sub-frame is better than what we have. LOL.

That is a very interesting and newer video. Two things that I seen was there seems to be the "V" clip installed and also there is no frame support gusset above the spring hangers.

Watched a few minutes of the video. I think I have more questions than answers.

1 - Just me, or did anyone else see the bottom flange damage in front of the middle hanger?
2 - Above the tires it appears that there has been contact between the tire and the repair tape (guessing this is an ongoing issue), or is that something else?
3 - Just a thought, but does anyone know if there has ever been a case study of using double swing shackles on the rear axle to prevent the axles from flexing the frame so bad? Would act allow slight variation in axle to axle distance during turns thus steering the camper.
4 - Why do frame MFG not box the frame above the axles?
5 - Is the camber of the frame due to the way it's loaded, or is there an underlying issue that needs to be addressed?

This is with less than 3 minutes of watching the video. It almost scares me to see such video's because we all know "IGNORANCE IS BLISS".

Joseph,

I captured video years ago under my rig and found that most lateral motion was on the center hangers. So I installed the Morryde X factor bracket and have not looked back. Heavier rigs should have V clips installed at a minimum on the rear hangers which exhibit the most failures.

Floor contact was an issue years ago with 3500 lb axles on larger models that now use 4400lb axles.

It is also important to note that the RV in the video is not a GD.

The lateral motion will be no different with this design from one make to another. There are two thoughts.

1) Make the system flexible and similar to what we have.

2) Make the system rigid like a Morryde or other systems that utilize a rigid sub-frame.

I would rather have a sub-frame and have the suspension system to be rigid.

Our flexible systems work well in general until the rear hangers begin to fail at the leading edge due to braking (spring wrap and reversal) and front axle rise which puts undo stress on the rear most hanger. Once the crack begins, the lateral load begins to work at the hanger until it completely fails. The V clips have been mostly effective in preventing this issue.
