2016 377 black diamond suspension issue

Am I alone in this case....dont think so... My rig is a 1 year old 2016 377 Black Diamond. During my first trip just after purchase, I noticed a severe tendancy to oversteer when turning left. A slight left turn always initiated a strong listing to the right. Upon troubleshooting I found the complete rig listing to the left by 3 inches and a half when static.

Under warranty, a specialized suspension shop were supposed to re-curve the leaf spring on the right. I was surprised when picking back my rig that they only added a 3 inches and a half shim to the right.

At that time, I did not liked the idea. I was right... Altough the RV was now level, the right rear leaf spring were almost flat compared to the curvy left ones. The result was that my oversteer to the left was still there (a leaf spring that goes negative curving when under load is pretty ineficient and scary). At the time of the first visit, they told me that an alignement was required after that kind of fix. I was glad because as you all know,alignement is an issue with those rigs. So back to the specialized shop under warranty and now they removed the shim on the rear right and added a taper leaf spring blade.

The result, oversteering to the left 90 percent better but now I have a rig that list 2 inches right at the front and level at the back. I do not think a front alignement was done this time as my steering is offset 5 deg to the right when going strait.

I am now waiting for the dealer to report this to the specialized shop and plan the next move. The dealer told me they never seen a situation like that but I dont beleive it .

Input from other owner would be appreciated aware of this issue because the drive could be dangerous when that condition arise.

I would say if the frame is strait and true you need a matching new set of leaf springs.. But like I said that is if the frame is correct and nothing has broken in the way of weld etc..
