Cracked cross member to pin box

I had this same problem about a year ago. I had the front cross member replaced and they welded a .25 in. thick plate on the face of the rear cross meber. they also added gussets between the pin box and the cross members. I have not have any more problems since the repair was completed. I just got back from a 11400 mile trip to Alaska and had no problems. I also filed a complaint with the NHTSA and have not heard a word from them. Good luck with your repairs,

Cracked pin box

Thanks for the infoTP. I heard back from Lippert and they have asked me to submit pictures we will see the full extent of the damage. They actually returned my call and called me because of a referal from my forest river call. They gave me a reference # so I feel I feel encouraged. Did you replace the cross member or put the .25 plate and gussets on the existing member? Oh by the way my error the trailer is a 2008. Denis

When I tried to also complain to the NHTSA. the person I talked to said they have not had any complaints or investigations on this matter. Start complaining and get your voices heard, or the RV industry will just get this swept under the bed.
Dale, They are yours. I was using them as "what to look for" when inspecting the pin box welds and crossbeam. Photo "ownership" seems to get smeared around a lot.

Lippert frame issue

Why don't more RVers band together to do a class action law suit against these RV maufactures who don't stand behind their products. I have a year warranty on my $15.00 dollar toaster, a years warranty on most of my under $100.00 house hold appliances. A year on a major purchase of an RV is at best a joke on consumers. I just wonder if there has been an accident out there caused by a Lippert frame failing??

Thumbs up Weld failure on Silverback

Hi, The day we bought our Silverback it had a crack on the left side on nose in gel coat, we were told by our dealer that they were not sure what had happened but, they turned it into Forest River and they repaired it. We took a nice long trip last summer and noticed at first that in the bedroom the trim was bent and we could see daylight in both corners of the front of the bedroom. Then when we got home we were washing it and noticed it had three cracks in gel coat, one by the door and two on the nose, one of them in the same spot that had been repaired. We sent pictures to Forest River and at first Forest River denied our claim telling us a bird must have hit us or a rock, humm, well we did some extensive research and found that the type of cracking was coming from inside of the nose and the side was a stress crack from twisting. We again contacted Forest River and told them we were going to persue the matter in court if we had to. They agreed to have the nose cap removed. Our dealer was no help and so we went to another Forest River dealer in town and when they picked the coach up with a fork lift after they had the nose cap off they noticed that the frame was flexing, they took a better look at it and it there were no welds in the center of the frame, and the two welds on both sides were broken and also part of the frame had cracks in it. Our coach is now in Indiana waiting its turn to be repaired. We were told by several RV techs that is it a wonder the nose of the 5th wheel didn't fall down on the bed of our truck. Not sure when we will get our coach back, at first they said Feb, but not sure. So far we have not had our coach for 2 months. We have searched the RV Forums and found a lot of people have had major issues with weld and frame failures on Lippert Frames. We are happy that they are going to fix it but, very upset that it happened in the first place.

Hope this helps others who perhaps face frame issues in Forest River products

Lippert Frame Defects

I had this same problem about 2 months ago. I had the front cross member replaced and they welded a plate on the face of the rear cross meber, They also added gussets between the pin box and the cross members. All of this original steel was .097" It was replaced with .250" steel .Also replaced the bedroom wall that was cracked from the frame pushing through. This was on a 2008 Toyhauler Cherokee Wolfpack W295 that was bought new and never had more than 2 quads in it weighing 900ibs total. Never towed behind it either. I have called Lippert

OK....heres what Ive seen in the last 12+ years of owning a camper....
When the Carlisle tires were blowing apart NOONE CONTACTED ANY RV OWNERS yet there were thousands of tires blowing and noone knew why...assumed was wera and tear and left it
When the axles were all welded off align and everyone was eating up tires in 2500 miles NOONE CONTACTED OWNERS TO INFORM THEM THEY WERE BAD....hundreds of people thought they just hit something.........
I truly dont believe there are any real rules pertaining to RV's as an industry governed by FMCSA....NHTSA...or DOT...Ive been with trucks for over 30 years and even a small issue is handled!.....I too have now got frame issues and they will NOT go unresolved...will keep all posted

Thumbs down Waiting for it to come home!!

Forest River called and told us our 2009 Silverback has been repaired and they have hired a transport co to transport it back here. We had wanted to go pick it up but, couldn't do it at this time. They rebuilt the front end and put gussets and straps to hold it and rewelded where the welds failed and welded where there were missing welds and , put new axles and tires on it as it had those nasty sealed bearings in it. Not sure when it will get here but, I hope soon, it has been in Indiana for 10 weeks, I sure hope it is fixed and we will have no more issues with it We have owned it for 16 months and it has been in the shop for almost three months, if everything is ok, and it is fixed I will then
I just fail to comprehend the lack of quality control and inspection of these RVs before they are sent out to the Dealers and purchased by consumers who are the ones who have to suffer from poor quality and workmanship. Not to mention the cost to Forest River for the return of units, and reputation of the Co.
