I'm the person who discovered this overweight problem back in Sept 2019, It was on a 2020 Oregon built Wolf Pup 18TO. I discovered that the 2020 model has a GWVR of 5625 and my 2019 Indiana built model GWVR of 4999. Upon investigating, I found that the two models had the same capacity tires, the same part numbers for frame, the same axle capacity of 5100 pounds and the same capacity of A frame coupler (5000 pound GVWR limit), so the 2020 Oregon 18TO was 625 pounds over gross weight. This I communicated to Forest River who soon stopped talking to me.
After being blown off by FR, I then contacted the NHTSA who then investigated and found the problem was a lot bigger than my model - some 328 units in all over several model lines.
The NHTSA notice indicated FR was considering a derate, so you owners may lose a lot of CCC. 625 pounds for 18TO owners!
I've written a letter to FR corporate compliance suggesting they replace the 5000 pound a frame coupler with an 7-8000 pound model, but it remains to be seen if this will have any effect. If FR continues to blow me off, I will go above them.
The real problem is lack of engineering support in the Cherokee division plant in Indiana. they only had one engineer who tries to keep up with all the changes but can't- there's too many model lines. When they initiated production in Oregon, they sent an incomplete set of drawings (no structural analysis, no electrical interconnection, no water interconnection and no wiring routing drawings - I got all of what they had when I visited the WOlf Pup factory last May and got a tour. So that's how it happened. Its no wonder they have a lot of recalls.
Maybe all of you who are affected may have more chance of getting their attention than I did.
